>Description:

In the Linux driver I saw that the Sierra cards support RTS/CTS. Adding support
for these signals might improve serial port performance when the host is busy.
U3G must handle high bit rates on a serial port infrastructure that has been
designed with 300 - 115k2 baud connections in mind.

Note: This is more or less a note to self.
>How-To-Repeat:
>Fix:

See the Linux driver for more information.
