Portions copied from the Keyspan driver by Hugh Blemings
- History:
-
- 2005-05-19 v0.1 Initial version, based on incomplete docs
- and analysis of misbehavior with the standard driver
- 2005-05-20 v0.2 Extended the input buffer to avoid losing
- random 64-byte chunks of data
- 2005-05-21 v0.3 implemented chars_in_buffer()
- turned on low_latency
- simplified the code somewhat
- 2005-05-24 v0.4 option_write() sometimes deadlocked under heavy load
- removed some dead code
- added sponsor notice
- coding style clean-up
- 2005-06-20 v0.4.1 add missing braces :-/
- killed end-of-line whitespace
- 2005-07-15 v0.4.2 rename WLAN product to FUSION, add FUSION2
- 2005-09-10 v0.4.3 added HUAWEI E600 card and Audiovox AirCard
- 2005-09-20 v0.4.4 increased recv buffer size: the card sometimes
- wants to send >2000 bytes.
- 2006-04-10 v0.5 fixed two array overrun errors :-/
- 2006-04-21 v0.5.1 added support for Sierra Wireless MC8755
- 2006-05-15 v0.6 re-enable multi-port support
- 2006-06-01 v0.6.1 add COBRA
- 2006-06-01 v0.6.2 add backwards-compatibility stuff
- 2006-06-01 v0.6.3 add Novatel Wireless
- 2006-06-01 v0.7 Option => GSM
- 2006-06-01 v0.7.1 add COBRA2
+ History: see the git log.

This driver exists because the "normal" serial driver doesn't work too well
with GSM modems. Issues:
- data loss -- one single Receive URB is not nearly enough
- - nonstandard flow (Option devices) and multiplex (Sierra) control
+ - nonstandard flow (Option devices) control
- controlling the baud rate doesn't make sense
This driver is named "option" because the most common device it's
