+ 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
+ - 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.
