- Option Card (PCMCIA to) USB to Serial Driver
+ USB Driver for GSM modems
Copyright (C) 2005 Matthias Urlichs <smurf@smurf.noris.de>
Portions copied from the Keyspan driver by Hugh Blemings <hugh@blemings.org>
- History:
+ History: see the git log.
- 2005-05-19 v0.1 Initial version, based on incomplete docs
- and analysis of misbehavior of 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
+ Work sponsored by: Sigos GmbH, Germany <info@sigos.de>
+
+ 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) control
+ - controlling the baud rate doesn't make sense
+
+ This driver is named "option" because the most common device it's
+ used for is a PC-Card (with an internal OHCI-USB interface, behind
+ which the GSM interface sits), made by Option Inc.
+
+ Some of the "one port" devices actually exhibit multiple USB instances
+ on the USB bus. This is not a bug, these ports are used for different
+ device features.
