menuconfig USB_SERIAL
tristate "USB Serial Converter support"
depends on TTY
---help---
Say Y here if you have a USB device that provides normal serial
ports, or acts like a serial device, and you want to connect it to
your USB bus.
Please read <file:Documentation/usb/usb-serial.txt> for more
information on the specifics of the different devices that are
supported, and on how to use them.
To compile this driver as a module, choose M here: the
module will be called usbserial.
if USB_SERIAL
config USB_SERIAL_CONSOLE
bool "USB Serial Console device support"
depends on USB_SERIAL=y
---help---
If you say Y here, it will be possible to use a USB to serial
converter port as the system console (the system console is the
device which receives all kernel messages and warnings and which
allows logins in single user mode). This could be useful if some
terminal or printer is connected to that serial port.
Even if you say Y here, the currently visible virtual console
(/dev/tty0) will still be used as the system console by default, but
you can alter that using a kernel command line option such as
"console=ttyUSB0". (Try "man bootparam" or see the documentation of
your boot loader (lilo or loadlin) about how to pass options to the
kernel at boot time.)
If you don't have a VGA card installed and you say Y here, the
kernel will automatically use the first USB to serial converter
port, /dev/ttyUSB0, as system console.
If unsure, say N.

*
* The device works as an standard CDC device, it has 2 interfaces, the first
* one is for firmware access and the second is the serial one.
* The protocol is very simply, there are two possibilities reading or writing.
* When writing the first urb must have a Header that starts with 0x20 0x29 the
* next two bytes must say how much data will be sent.
* When reading the process is almost equal except that the header starts with
* 0x00 0x20.
*
* The device simply need some stuff to understand data coming from the usb
* buffer: The First and Second byte is used for a Header, the Third and Fourth
* tells the device the amount of information the package holds.
* Packages are 60 bytes long Header Stuff.
* When writing to the device the first two bytes of the header are 0x20 0x29
* When reading the bytes are 0x00 0x20, or 0x00 0x10, there is an strange
* situation, when too much data arrives to the device because it sends the data
* but with out the header. I will use a simply hack to override this situation,
* if there is data coming that does not contain any header, then that is data
* that must go directly to the tty, as there is no documentation about if there
* is any other control code, I will simply check for the first
* one.
*
* The driver registers himself with the USB-serial core and the USB Core. I had
* to implement a probe function against USB-serial, because other way, the
* driver was attaching himself to both interfaces. I have tried with different
* configurations of usb_serial_driver with out exit, only the probe function
* could handle this correctly.
*
* I have taken some info from a Greg Kroah-Hartman article:
* http://www.linuxjournal.com/article/6573
* And from Linux Device Driver Kit CD, which is a great work, the authors taken
* the work to recompile lots of information an knowledge in drivers development
* and made it all available inside a cd.

* ark3116
* - implements a driver for the arkmicro ark3116 chipset (vendor=0x6547,
* productid=0x0232) (used in a datacable called KQ-U8A)
*
* Supports full modem status lines, break, hardware flow control. Does not

*
* This driver is a essentially new implementation. I initially dug

/*
* The following describes what I learned from studying the old
* ark3116.c driver, disassembling the windows driver, and some lucky
* guesses. Since I do not have any datasheet or other
* documentation, inaccuracies are almost guaranteed.
*
* Some specs for the ARK3116 can be found here:
* http://web.archive.org/web/20060318000438/
* www.arkmicro.com/en/products/view.php?id=10
* On that page, 2 GPIO pins are mentioned: I assume these are the
* OUT1 and OUT2 pins of the UART, so I added support for those
* through the MCR. Since the pins are not available on my hardware,
* I could not verify this.
* Also, it states there is "on-chip hardware flow control". I have
* discovered how to enable that. Unfortunately, I do not know how to
* enable XON/XOFF (software) flow control, which would need support
* from the chip as well to work. Because of the wording on the web
* page there is a real possibility the chip simply does not support
* software flow control.
*
* I got my ark3116 as part of a mobile phone adapter cable. On the
* PCB, the following numbered contacts are present:
*
* 1:- +5V
* 2:o DTR
* 3:i RX
* 4:i DCD
* 5:o RTS
* 6:o TX
* 7:i RI
* 8:i DSR
* 10:- 0V
* 11:i CTS
*
* On my chip, all signals seem to be 3.3V, but 5V tolerant. But that
* may be different for the one you have ;-).
*
* The windows driver limits the registers to 0-F, so I assume there
* are actually 16 present on the device.
*
* On an UART interrupt, 4 bytes of data come in on the interrupt
* endpoint. The bytes are 0xe8 IIR LSR MSR.
*
* The baudrate seems to be generated from the 12MHz crystal, using
* 4-times subsampling. So quot=12e6/(4*baud). Also see description
* of register E.
*
* Registers 0-7:
* These seem to be the same as for a regular 16450. The FCR is set
* to UART_FCR_DMA_SELECT (0x8), I guess to enable transfers between
* the UART and the USB bridge/DMA engine.
*
* Register 8:
* By trial and error, I found out that bit 0 enables hardware CTS,
* stopping TX when CTS is +5V. Bit 1 does the same for RTS, making
* RTS +5V when the 3116 cannot transfer the data to the USB bus
* (verified by disabling the reading URB). Note that as far as I can
* tell, the windows driver does NOT use this, so there might be some
* hardware bug or something.
*
* According to a patch provided here
* (http://lkml.org/lkml/2009/7/26/56), the ARK3116 can also be used
* as an IrDA dongle. Since I do not have such a thing, I could not
* investigate that aspect. However, I can speculate ;-).
*
* - IrDA encodes data differently than RS232. Most likely, one of
* the bits in registers 9..E enables the IR ENDEC (encoder/decoder).
* - Depending on the IR transceiver, the input and output need to be
* inverted, so there are probably bits for that as well.
* - IrDA is half-duplex, so there should be a bit for selecting that.
*
* This still leaves at least two registers unaccounted for. Perhaps
* The chip can do XON/XOFF or CRC in HW?
*
* Register 9:
* Set to 0x00 for IrDA, when the baudrate is initialised.
*
* Register A:
* Set to 0x01 for IrDA, at init.
*
* Register B:
* Set to 0x01 for IrDA, 0x00 for RS232, at init.
*
* Register C:
* Set to 00 for IrDA, at init.
*
* Register D:
* Set to 0x41 for IrDA, at init.
*
* Register E:
* Somekind of baudrate override. The windows driver seems to set
* this to 0x00 for normal baudrates, 0x01 for 460800, 0x02 for 921600.
* Since 460800 and 921600 cannot be obtained by dividing 3MHz by an integer,
* it could be somekind of subdivisor thingy.
* However,it does not seem to do anything: selecting 921600 (divisor 3,
* reg E=2), still gets 1 MHz. I also checked if registers 9, C or F would
* work, but they don't.
*
* Register F: unknown

*
* The example I have is known as the USC-1000 which is available from

*
* The device is based on the FTDI FT8U100AX chip. It has a DB25 on one side,
* USB on the other.
*
* Thanx to FTDI (http://www.ftdichip.com) for so kindly providing details

* BmRequestType: 0100 0000B
* bRequest: FTDI_SIO_SET_BAUDRATE
* wValue: BaudDivisor value - see below
* wIndex: Port
* wLength: 0
* Data: None
* The BaudDivisor values are calculated as follows:
* - BaseClock is either 12000000 or 48000000 depending on the device.
* FIXME: I wish I knew how to detect old chips to select proper base clock!
* - BaudDivisor is a fixed point number encoded in a funny way.
* (--WRONG WAY OF THINKING--)
* BaudDivisor is a fixed point number encoded with following bit weighs:
* (-2)(-1)(13..0). It is a radical with a denominator of 4, so values
* end with 0.0 (00...), 0.25 (10...), 0.5 (01...), and 0.75 (11...).
* (--THE REALITY--)
* The both-bits-set has quite different meaning from 0.75 - the chip
* designers have decided it to mean 0.125 instead of 0.75.
* This info looked up in FTDI application note "FT8U232 DEVICES \ Data Rates
* and Flow Control Consideration for USB to RS232".
* - BaudDivisor = (BaseClock / 16) / BaudRate, where the (=) operation should
* automagically re-encode the resulting value to take fractions into
* consideration.
* As all values are integers, some bit twiddling is in order:
* BaudDivisor = (BaseClock / 16 / BaudRate) |
* (((BaseClock / 2 / BaudRate) & 4) ? 0x4000 // 0.5
* : ((BaseClock / 2 / BaudRate) & 2) ? 0x8000 // 0.25
* : ((BaseClock / 2 / BaudRate) & 1) ? 0xc000 // 0.125
* : 0)
*
* For the FT232BM, a 17th divisor bit was introduced to encode the multiples
* of 0.125 missing from the FT8U232AM. Bits 16 to 14 are coded as follows
* (the first four codes are the same as for the FT8U232AM, where bit 16 is
* always 0):
* 000 - add .000 to divisor
* 001 - add .500 to divisor
* 010 - add .250 to divisor
* 011 - add .125 to divisor
* 100 - add .375 to divisor
* 101 - add .625 to divisor
* 110 - add .750 to divisor
* 111 - add .875 to divisor
* Bits 15 to 0 of the 17-bit divisor are placed in the urb value. Bit 16 is
* placed in bit 0 of the urb index.
*
* Note that there are a couple of special cases to support the highest baud
* rates. If the calculated divisor value is 1, this needs to be replaced with
* 0. Additionally for the FT232BM, if the calculated divisor value is 0x4001
* (1.5), this needs to be replaced with 0x0001 (1) (but this divisor value is
* not supported by the FT8U232AM).

/************************************************************************
The data to and from all ports on the peripheral is multiplexed
through a single endpoint pair (EP1 since it supports 64-byte
MaxPacketSize). Therefore, the data, commands, and status for
each port must be preceded by a short header identifying the
destination port. The header also identifies the bytes that follow
as data or as command/status info.
Header format, first byte:
CLLLLPPP
--------
| | |------ Port Number: 0-7
| |--------- Length: MSB bits of length
|----------- Data/Command: 0 = Data header
1 = Cmd / Status (Cmd if OUT, Status if IN)
This gives 2 possible formats:
Data header: 0LLLLPPP LLLLLLLL
============
Where (LLLL,LLLLLLL) is 12-bit length of data that follows for
port number (PPP). The length is 0-based (0-FFF means 0-4095
bytes). The ~4K limit allows the host driver (which deals in
transfer requests instead of individual packets) to write a
large chunk of data in a single request. Note, however, that
the length must always be <= the current TxCredits for a given
port due to buffering limitations on the peripheral.
Cmd/Status header: 1ccccPPP [ CCCCCCCC, Params ]...
==================
Where (cccc) or (cccc,CCCCCCCC) is the cmd or status identifier.
Frequently-used values are encoded as (cccc), longer ones using
(cccc,CCCCCCCC). Subsequent bytes are optional parameters and are
specific to the cmd or status code. This may include a length
for command and status codes that need variable-length parameters.
In addition, we use another interrupt pipe (endpoint) which the host polls
periodically for flow control information. The peripheral, when there has
been a change, sends the following 10-byte packet:
RRRRRRRRRRRRRRRR
T0T0T0T0T0T0T0T0
T1T1T1T1T1T1T1T1
T2T2T2T2T2T2T2T2
T3T3T3T3T3T3T3T3
The first field is the 16-bit RxBytesAvail field, which indicates the
number of bytes which may be read by the host from EP1. This is necessary:
(a) because OSR2.1 has a bug which causes data loss if the peripheral returns
fewer bytes than the host expects to read, and (b) because, on Microsoft
platforms at least, an outstanding read posted on EP1 consumes about 35% of
the CPU just polling the device for data.
The next 4 fields are the 16-bit TxCredits for each port, which indicate how
many bytes the host is allowed to send on EP1 for transmit to a given port.
After an OPEN_PORT command, the Edgeport sends the initial TxCredits for that
port.
All 16-bit fields are sent in little-endian (Intel) format.

// the last Tx char leaves the UART.
// Not currently implemented by firmware.
//
// IOSP_CMD_SET_XON_CHAR
//
// Sets the character which Edgeport transmits/interprets as XON.

// Example for Port 0

// P0 = 11001000
// P1 = IOSP_CMD_SET_XOFF_CHAR
// P2 = 0x13
//
// IOSP_CMD_RX_CHECK_REQ
//
// This command is used to assist in the implementation of the
// IOCTL_SERIAL_PURGE Windows IOCTL.
// This IOSP command tries to place a marker at the end of the RX
// queue in the Edgeport. If the Edgeport RX queue is full then
// the Check will be discarded.
// It is up to the device driver to timeout waiting for the
// RX_CHECK_RSP. If a RX_CHECK_RSP is received, the driver is
// sure that all data has been received from the edgeport and
// may now purge any internal RX buffers.
// Note tat the sequence numbers may be used to detect lost
// CHECK_REQs.
// Example for Port 0
// P0 = 11001000
// P1 = IOSP_CMD_RX_CHECK_REQ
// P2 = Sequence number
// Response will be:
// P1 = IOSP_EXT_RX_CHECK_RSP

*
* All information about the device was acquired using SnoopyPro
* on MSFT's O/S, and examing the MSFT drivers' debug output
* (insanely left _on_ in the enduser version)
*
* It was written out of frustration with the IPWireless USB modem
* supplied by Axity3G/Sentech South Africa not supporting
* Linux whatsoever.
*
* Nobody provided any proprietary information that was not already
* available for this device.
*
* The modem adheres to the "3GPP TS 27.007 AT command set for 3G
* User Equipment (UE)" standard, available from
* http://www.3gpp.org/ftp/Specs/html-info/27007.htm
*
* The code was only tested the IPWireless handheld modem distributed
* in South Africa by Sentech.
*
* It may work for Woosh Inc in .nz too, as it appears they use the
* same kit.
*
* There is still some work to be done in terms of handling
* DCD, DTR, RTS, CTS which are currently faked.
* It's good enough for PPP at this point. It's based off all kinds of
* code found in usb/serial and usb/class

Code in this driver inspired by and in a number of places taken
from Brian Warner's original Keyspan-PDA driver.
This driver has been put together with the support of Innosys, Inc.
and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
Thanks Guys :)
Thanks to Paulus for miscellaneous tidy ups, some largish chunks
of much nicer and/or completely new code and (perhaps most uniquely)
having the patience to sit down and explain why and where he'd changed
stuff.
Tip 'o the hat to IBM (and previously Linuxcare :) for supporting
staff in their work on open source projects.
See keyspan.c for update history.

Third revision: USA28X version (aka USA26)
Buffer formats for RX/TX data messages are not defined by
a structure, but are described here:
USB OUT (host -> USAxx, transmit) messages contain a
REQUEST_ACK indicator (set to 0xff to request an ACK at the
completion of transmit; 0x00 otherwise), followed by data:
RQSTACK DAT DAT DAT ...
with a total data length of 63.
USB IN (USAxx -> host, receive) messages begin with a status
byte in which the 0x80 bit is either:
(a) 0x80 bit clear
indicates that the bytes following it are all data
bytes:
STAT DATA DATA DATA DATA DATA ...
for a total of up to 63 DATA bytes,
or:
(b) 0x80 bit set
indicates that the bytes following alternate data and
status bytes:
STAT DATA STAT DATA STAT DATA STAT DATA ...
for a total of up to 32 DATA bytes.
The valid bits in the STAT bytes are:
OVERRUN 0x02
PARITY 0x04
FRAMING 0x08
BREAK 0x10
Notes:
(1) The OVERRUN bit can appear in either (a) or (b) format
messages, but the but the PARITY/FRAMING/BREAK bits
only appear in (b) format messages.
(2) For the host to determine the exact point at which the
overrun occurred (to identify the point in the data
stream at which the data was lost), it needs to count
128 characters, starting at the first character of the
message in which OVERRUN was reported; the lost character(s)
would have been received between the 128th and 129th
characters.
(3) An RX data message in which the first byte has 0x80 clear
serves as a "break off" indicator.
revision history:
1999feb10 add reportHskiaChanges to allow us to ignore them
1999feb10 add txAckThreshold for fast+loose throughput enhancement
1999mar30 beef up support for RX error reporting
1999apr14 add resetDataToggle to control message
2000jan04 merge with usa17msg.h
2000jun01 add extended BSD-style copyright text
2001jul05 change message format to improve OVERRUN case
Note on shared names:
In the case of fields which have been merged between the USA17
and USA26 definitions, the USA26 definition is the first part
of the name and the USA17 definition is the second part of the
name; both meanings are described below.

Note: these message formats are common to USA18, USA19, and USA28;
(for USA28X, see usa26msg.h)
Buffer formats for RX/TX data messages are not defined by
a structure, but are described here:
USB OUT (host -> USA28, transmit) messages contain a
REQUEST_ACK indicator (set to 0xff to request an ACK at the
completion of transmit; 0x00 otherwise), followed by data.
If the port is configured for parity, the data will be an
alternating string of parity and data bytes, so the message
format will be:
RQSTACK PAR DAT PAR DAT ...
so the maximum length is 63 bytes (1 + 62, or 31 data bytes);
always an odd number for the total message length.
If there is no parity, the format is simply:
RQSTACK DAT DAT DAT ...
with a total data length of 63.
USB IN (USA28 -> host, receive) messages contain data and parity
if parity is configred, thusly:
DAT PAR DAT PAR DAT PAR ...
for a total of 32 data bytes;
If parity is not configured, the format is:
DAT DAT DAT ...
for a total of 64 data bytes.
In the TX messages (USB OUT), the 0x01 bit of the PARity byte is
the parity bit. In the RX messages (USB IN), the PARity byte is
the content of the 8051's status register; the parity bit
(RX_PARITY_BIT) is the 0x04 bit.

4th revision: USA49W version
Buffer formats for RX/TX data messages are not defined by
a structure, but are described here:
USB OUT (host -> USAxx, transmit) messages contain a
REQUEST_ACK indicator (set to 0xff to request an ACK at the
completion of transmit; 0x00 otherwise), followed by data:
RQSTACK DAT DAT DAT ...
with a total data length of 63.
USB IN (USAxx -> host, receive) messages begin with a status
byte in which the 0x80 bit is either:
(a) 0x80 bit clear
indicates that the bytes following it are all data
bytes:
STAT DATA DATA DATA DATA DATA ...
for a total of up to 63 DATA bytes,
or:
(b) 0x80 bit set
indiates that the bytes following alternate data and
status bytes:
STAT DATA STAT DATA STAT DATA STAT DATA ...
for a total of up to 32 DATA bytes.
The valid bits in the STAT bytes are:
OVERRUN 0x02
PARITY 0x04
FRAMING 0x08
BREAK 0x10
Notes:
(1) The OVERRUN bit can appear in either (a) or (b) format
messages, but the but the PARITY/FRAMING/BREAK bits
only appear in (b) format messages.
(2) For the host to determine the exact point at which the
overrun occurred (to identify the point in the data
stream at which the data was lost), it needs to count
128 characters, starting at the first character of the
message in which OVERRUN was reported; the lost character(s)
would have been received between the 128th and 129th
characters.
(3) An RX data message in which the first byte has 0x80 clear
serves as a "break off" indicator.
(4) a control message specifying disablePort will be answered
with a status message, but no further status will be sent
until a control messages with enablePort is sent

* All information about the device was acquired using SniffUSB ans snoopUSB

* It was written out of frustration with the PalmConnect USB Serial adapter
* sold by Palm Inc.
* Neither Palm, nor their contractor (MCCI) or their supplier (KLSI) provided
* information that was not already available.
*
* It seems that KLSI bought some silicon-design information from ScanLogic,
* whose SL11R processor is at the core of the KL5KUSB chipset from KLSI.
* KLSI has firmware available for their devices; it is probable that the
* firmware differs from that used by KLSI in their products. If you have an
* original KLSI device and can provide some information on it, I would be
* most interested in adding support for it here. If you have any information
* on the protocol used (or find errors in my reverse-engineered stuff), please
* let me know.
*
* The code was only tested with a PalmConnect USB adapter; if you
* are adventurous, try it with any KLSI-based device and let me know how it
* breaks so that I can fix it!

* William G. Greathouse and Greg Kroah-Hartman provided great help on how to

always sends two extra USB 'device request' messages after the
'baud rate change' message. The actual functionality of the
request codes in these messages is not fully understood but these
particular codes are never seen in any operation besides a baud
rate change. Both of these messages send a single byte of data.
In the first message, the value of this byte is always zero.
The second message has been determined experimentally to control
whether data will be transmitted to a device which is not asserting
the 'CTS' signal. If the second message's data byte is zero, data
will be transmitted even if 'CTS' is not asserted (i.e. no hardware
flow control). if the second message's data byte is nonzero (a
value of 1 is used by this driver), data will not be transmitted to
a device which is not asserting 'CTS'.

/* -----------------------------------------------------------------------------
* Technical Specification reverse engineered with SniffUSB on Windows98
* =====================================================================
*
* The technical details of the device have been acquired be using "SniffUSB"
* and the vendor-supplied device driver (version 2.3A) under Windows98. To
* identify the USB vendor-specific requests and to assign them to terminal
* settings (flow control, baud rate, etc.) the program "SerialSettings" from
* William G. Greathouse has been proven to be very useful. I also used the
* Win98 "HyperTerminal" and "usb-robot" on Linux for testing. The results and
* observations are summarized below:
*
* The USB requests seem to be directly mapped to the registers of a 8250,
* 16450 or 16550 UART. The FreeBSD handbook (appendix F.4 "Input/Output
* devices") contains a comprehensive description of UARTs and its registers.
* The bit descriptions are actually taken from there.
*
*
* Baud rate (divisor)
* -------------------
*
* BmRequestType: 0x40 (0100 0000B)
* bRequest: 0x05
* wValue: 0x0000
* wIndex: 0x0000
* wLength: 0x0004
* Data: divisor = 115200 / baud_rate
*
* SniffUSB observations (Nov 2003): Contrary to the 'wLength' value of 4
* shown above, observations with a Belkin F5U109 adapter, using the
* MCT-supplied Windows98 driver (U2SPORT.VXD, "File version: 1.21P.0104 for
* Win98/Me"), show this request has a length of 1 byte, presumably because
* of the fact that the Belkin adapter and the 'Sitecom U232-P25' adapter
* use a baud-rate code instead of a conventional RS-232 baud rate divisor.
* The current source code for this driver does not reflect this fact, but
* the driver works fine with this adapter/driver combination nonetheless.
*
*
* Line Control Register (LCR)
* ---------------------------
*
* BmRequestType: 0x40 (0100 0000B) 0xc0 (1100 0000B)
* bRequest: 0x07 0x06
* wValue: 0x0000
* wIndex: 0x0000
* wLength: 0x0001
* Data: LCR (see below)
*
* Bit 7: Divisor Latch Access Bit (DLAB). When set, access to the data
* transmit/receive register (THR/RBR) and the Interrupt Enable Register
* (IER) is disabled. Any access to these ports is now redirected to the
* Divisor Latch Registers. Setting this bit, loading the Divisor
* Registers, and clearing DLAB should be done with interrupts disabled.
* Bit 6: Set Break. When set to "1", the transmitter begins to transmit
* continuous Spacing until this bit is set to "0". This overrides any
* bits of characters that are being transmitted.
* Bit 5: Stick Parity. When parity is enabled, setting this bit causes parity
* to always be "1" or "0", based on the value of Bit 4.
* Bit 4: Even Parity Select (EPS). When parity is enabled and Bit 5 is "0",
* setting this bit causes even parity to be transmitted and expected.
* Otherwise, odd parity is used.
* Bit 3: Parity Enable (PEN). When set to "1", a parity bit is inserted
* between the last bit of the data and the Stop Bit. The UART will also
* expect parity to be present in the received data.
* Bit 2: Number of Stop Bits (STB). If set to "1" and using 5-bit data words,
* 1.5 Stop Bits are transmitted and expected in each data word. For
* 6, 7 and 8-bit data words, 2 Stop Bits are transmitted and expected.
* When this bit is set to "0", one Stop Bit is used on each data word.
* Bit 1: Word Length Select Bit #1 (WLSB1)
* Bit 0: Word Length Select Bit #0 (WLSB0)
* Together these bits specify the number of bits in each data word.
* 1 0 Word Length
* 0 0 5 Data Bits
* 0 1 6 Data Bits
* 1 0 7 Data Bits
* 1 1 8 Data Bits
*
* SniffUSB observations: Bit 7 seems not to be used. There seem to be two bugs
* in the Win98 driver: the break does not work (bit 6 is not asserted) and the
* stick parity bit is not cleared when set once. The LCR can also be read
* back with USB request 6 but this has never been observed with SniffUSB.
*
*
* Modem Control Register (MCR)
* ----------------------------
*
* BmRequestType: 0x40 (0100 0000B)
* bRequest: 0x0a
* wValue: 0x0000
* wIndex: 0x0000
* wLength: 0x0001
* Data: MCR (Bit 4..7, see below)
*
* Bit 7: Reserved, always 0.
* Bit 6: Reserved, always 0.
* Bit 5: Reserved, always 0.
* Bit 4: Loop-Back Enable. When set to "1", the UART transmitter and receiver
* are internally connected together to allow diagnostic operations. In
* addition, the UART modem control outputs are connected to the UART
* modem control inputs. CTS is connected to RTS, DTR is connected to
* DSR, OUT1 is connected to RI, and OUT 2 is connected to DCD.
* Bit 3: OUT 2. An auxiliary output that the host processor may set high or
* low. In the IBM PC serial adapter (and most clones), OUT 2 is used
* to tri-state (disable) the interrupt signal from the
* 8250/16450/16550 UART.
* Bit 2: OUT 1. An auxiliary output that the host processor may set high or
* low. This output is not used on the IBM PC serial adapter.
* Bit 1: Request to Send (RTS). When set to "1", the output of the UART -RTS
* line is Low (Active).
* Bit 0: Data Terminal Ready (DTR). When set to "1", the output of the UART
* -DTR line is Low (Active).
*
* SniffUSB observations: Bit 2 and 4 seem not to be used but bit 3 has been
* seen _always_ set.
*
*
* Modem Status Register (MSR)
* ---------------------------
*
* BmRequestType: 0xc0 (1100 0000B)
* bRequest: 0x02
* wValue: 0x0000
* wIndex: 0x0000
* wLength: 0x0001
* Data: MSR (see below)
*
* Bit 7: Data Carrier Detect (CD). Reflects the state of the DCD line on the
* UART.
* Bit 6: Ring Indicator (RI). Reflects the state of the RI line on the UART.
* Bit 5: Data Set Ready (DSR). Reflects the state of the DSR line on the UART.
* Bit 4: Clear To Send (CTS). Reflects the state of the CTS line on the UART.
* Bit 3: Delta Data Carrier Detect (DDCD). Set to "1" if the -DCD line has
* changed state one more more times since the last time the MSR was
* read by the host.
* Bit 2: Trailing Edge Ring Indicator (TERI). Set to "1" if the -RI line has
* had a low to high transition since the last time the MSR was read by
* the host.
* Bit 1: Delta Data Set Ready (DDSR). Set to "1" if the -DSR line has changed
* state one more more times since the last time the MSR was read by the
* host.
* Bit 0: Delta Clear To Send (DCTS). Set to "1" if the -CTS line has changed
* state one more times since the last time the MSR was read by the
* host.
*
* SniffUSB observations: the MSR is also returned as first byte on the
* interrupt-in endpoint 0x83 to signal changes of modem status lines. The USB
* request to read MSR cannot be applied during normal device operation.
*
*
* Line Status Register (LSR)
* --------------------------
*
* Bit 7 Error in Receiver FIFO. On the 8250/16450 UART, this bit is zero.
* This bit is set to "1" when any of the bytes in the FIFO have one
* or more of the following error conditions: PE, FE, or BI.
* Bit 6 Transmitter Empty (TEMT). When set to "1", there are no words
* remaining in the transmit FIFO or the transmit shift register. The
* transmitter is completely idle.
* Bit 5 Transmitter Holding Register Empty (THRE). When set to "1", the
* FIFO (or holding register) now has room for at least one additional
* word to transmit. The transmitter may still be transmitting when
* this bit is set to "1".
* Bit 4 Break Interrupt (BI). The receiver has detected a Break signal.
* Bit 3 Framing Error (FE). A Start Bit was detected but the Stop Bit did
* not appear at the expected time. The received word is probably
* garbled.
* Bit 2 Parity Error (PE). The parity bit was incorrect for the word
* received.
* Bit 1 Overrun Error (OE). A new word was received and there was no room
* in the receive buffer. The newly-arrived word in the shift register
* is discarded. On 8250/16450 UARTs, the word in the holding register
* is discarded and the newly- arrived word is put in the holding
* register.
* Bit 0 Data Ready (DR). One or more words are in the receive FIFO that the
* host may read. A word must be completely received and moved from
* the shift register into the FIFO (or holding register for
* 8250/16450 designs) before this bit is set.
*
* SniffUSB observations: the LSR is returned as second byte on the
* interrupt-in endpoint 0x83 to signal error conditions. Such errors have
* been seen with minicom/zmodem transfers (CRC errors).
*
*
* Unknown #1
* -------------------
*
* BmRequestType: 0x40 (0100 0000B)
* bRequest: 0x0b
* wValue: 0x0000
* wIndex: 0x0000
* wLength: 0x0001
* Data: 0x00
*
* SniffUSB observations (Nov 2003): With the MCT-supplied Windows98 driver
* (U2SPORT.VXD, "File version: 1.21P.0104 for Win98/Me"), this request
* occurs immediately after a "Baud rate (divisor)" message. It was not
* observed at any other time. It is unclear what purpose this message
* serves.
*
*
* Unknown #2
* -------------------
*
* BmRequestType: 0x40 (0100 0000B)
* bRequest: 0x0c
* wValue: 0x0000
* wIndex: 0x0000
* wLength: 0x0001
* Data: 0x00
*
* SniffUSB observations (Nov 2003): With the MCT-supplied Windows98 driver
* (U2SPORT.VXD, "File version: 1.21P.0104 for Win98/Me"), this request
* occurs immediately after the 'Unknown #1' message (see above). It was
* not observed at any other time. It is unclear what other purpose (if
* any) this message might serve, but without it, the USB/RS-232 adapter
* will not write to RS-232 devices which do not assert the 'CTS' signal.
*
*
* Flow control
* ------------
*
* SniffUSB observations: no flow control specific requests have been realized
* apart from DTR/RTS settings. Both signals are dropped for no flow control
* but asserted for hardware or software flow control.
*
*
* Endpoint usage
* --------------
*
* SniffUSB observations: the bulk-out endpoint 0x1 and interrupt-in endpoint
* 0x81 is used to transmit and receive characters. The second interrupt-in
* endpoint 0x83 signals exceptional conditions like modem line changes and
* errors. The first byte returned is the MSR and the second byte the LSR.
*
*
* Other observations
* ------------------
*
* Queued bulk transfers like used in visor.c did not work.

* know this because there is a sticky label on the circuit board
* which says "U232-P9" ;-)
*
* The circuit board inside the adaptor contains a Philips PDIUSBD12
* USB endpoint chip and a Philips P87C52UBAA microcontroller with
* embedded UART. Exhaustive documentation for these is available at:

* Many thanks to the authors of pl2303 driver: all functions in this file
* are heavily based on pl2303 code, buffering code is a 1-to-1 copy.
*
* Warning! You use this driver on your own risk! The only official
* description of this device I have is datasheet from manufacturer,
* and it doesn't contain almost any information needed to write a driver.
* Almost all knowlegde used while writing this driver was gathered by:
* - analyzing traffic between device and the M$ Windows 2000 driver,
* - trying different bit combinations and checking pin states
* with a voltmeter,
* - receiving malformed frames and producing buffer overflows
* to learn how errors are reported,
* So, THIS CODE CAN DESTROY OTi-6858 AND ANY OTHER DEVICES, THAT ARE
* CONNECTED TO IT!

*
* See Documentation/usb/usb-serial.txt for more information on using this
* driver
*
* TODO:
* - implement correct flushing for ioctls and oti6858_close()
* - check how errors (rx overflow, parity error, framing error) are reported
* - implement oti6858_break_ctl()
* - implement more ioctls
* - test/implement flow control
* - allow setting custom baud rates

/*
* The encapsultaion is designed to overcome difficulties with some USB
* hardware.
*
* While the USB protocol has a CRC over the data while in transit, i.e. while
* being carried over the bus, there is no end to end protection. If the
* hardware has any problems getting the data into or out of the USB transmit
* and receive FIFO's then data can be lost.
*
* This protocol adds a two byte trailer to each USB packet to specify the
* number of bytes of valid data and a 10 bit CRC that will allow the receiver
* to verify that the entire USB packet was received without error.
*
* Because in this case the sender and receiver are the class and function
* drivers there is now end to end protection.
*
* There is an additional option that can be used to force all transmitted
* packets to be padded to the maximum packet size. This provides a work
* around for some devices which have problems with small USB packets.
*
* Assuming a packetsize of N:
*
* 0..N-2 data and optional padding
*
* N-2 bits 7-2 - number of bytes of valid data
* bits 1-0 top two bits of 10 bit CRC
* N-1 bottom 8 bits of 10 bit CRC
*
*
* | Data Length | 10 bit CRC |
* + 7 . 6 . 5 . 4 . 3 . 2 . 1 . 0 | 7 . 6 . 5 . 4 . 3 . 2 . 1 . 0 +
*
* The 10 bit CRC is computed across the sent data, followed by the trailer
* with the length set and the CRC set to zero. The CRC is then OR'd into
* the trailer.
*
* When received a 10 bit CRC is computed over the entire frame including
* the trailer and should be equal to zero.
*
* Two module parameters are used to control the encapsulation, if both are
* turned of the module works as a simple serial device with NO
* encapsulation.
*
* See linux/drivers/usbd/serial_fd for a device function driver
* implementation of this.

This driver exists because the "normal" serial driver doesn't work too well

- data loss -- one single Receive URB is not nearly enough
