PCTel HSP Modem not supported out of the box (or at all)

[Martijn vdS]

My PCTel HSP Modem is not supported. It's the only non-supported piece of
hardware left in my laptop (and yes, I know it's a winmodem)

0000:00:09.0 Communication controller: PCTel Inc HSP MicroModem 56 (rev 01)
        Subsystem: PCTel Inc PCT789 adapter
        Flags: medium devsel, IRQ 9
        I/O ports at 2000 [size=64]
        Capabilities: [40] Power Management version 2

There's a driver for 2.4 kernels, but it (a) doesn't build on 2.6, and (b)
appears to violate the GPL in several ways. Hm.

[Ben Collins (ben-collins)]

The driver for this bit of hardware is not really something we can distribute.
For reference, you can find it here though:
