Portions copied from the Keyspan driver by Hugh Blemings History: see the git log. Work sponsored by: Sigos GmbH, Germany 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. */ #define DRIVER_VERSION "v0.7.2" #define DRIVER_AUTHOR "Matthias Urlichs " #define DRIVER_DESC "USB Driver for GSM modems"
