Code in this driver inspired by and in a number of places taken
from Brian Warner's original Keyspan-PDA driver.
This driver has been put together with the support of Innosys, Inc.
and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
Thanks Guys :)

Thanks to Paulus for miscellaneous tidy ups, some largish chunks
of much nicer and/or completely new code and (perhaps most uniquely)
having the patience to sit down and explain why and where he'd changed
- stuff.

- Tip 'o the hat to IBM (and previously Linuxcare :) for supporting
+ stuff.

Merged Paul's changes with my USA-49W mods. Work in progress
still...
-

Wed Jul 19 14:00:42 EST 2000 gkh
Added module_init and module_exit functions to handle the fact that
this driver is a loadable module now.

Basic character input/output for USA-19 now mostly works,
fixed at 9600 baud for the moment.
