I was just poking around on the Web, and found that ComTrol has a
publicly available copy of the source code from their developer's
kit. It is at ftp://ftp.comtrol.com/BETA/DRVSAM.zip. This contains all
the C macros and functions that someone I knew used to make a RocketPort
driver for a proprietary (but ver BSD 4.4'ish in many ways) driver for
the RocketPort.

The copyright on the code reads like this:

/***********************************************************************

I don't know how much constitute "portions", so I'm not sure if this
would cause a conflict with the philosophy of distributing full source
or not.

Anyway, if anyone is interested in making a RocketPort driver for NetBSD
(or any other *BSD, for that matter), there is the code you need, and I
may be able to find you a good deal on a RocketPort too, if you need one
(we are no longer using them since we became part of Ascend).
