Say Y here if you want to use an Option card. This is a
GSM card, controlled by three serial ports which are connected
via an OHCI adapter located on a PC card.
Say Y here if you have an "Option" GSM PCMCIA card
(or an OEM version: branded Huawei, Audiovox, or Novatel).

These cards feature a built-in OHCI-USB adapter and an
internally-connected GSM modem. The USB bus is not
accessible externally.

To compile this driver as a module, choose M here: the
module will be called option.

If this driver doesn't recognize your device,
it might be accessible via the FTDI_SIO driver.

2006-06-01 v0.6.3 add Novatel Wireless
2006-06-01 v0.7 Option => GSM
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) 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.
