RigBlaster and FreeBSD

I've looked over the West Mountain website and I can't see anything
about how to make the RigBlaster run on FreeBSD. It's something I'd
need to know before buying one, obviously. Anyone here have any
experience with something like this?

Since we're not in an airport, I feel free to say this:

Hi, Jack.

If it'll run on Linux, then the Linux-compatibility stuff in
FreeBSD will run it very nicely -- except for a _very_ few
things.

The rigblaster just uses the DTR and RTS signals of a serial port.

Here's some code I wrote in Linux to play with mine. It basically
just changes the state of the DTR and RTS signals.

*
* The RTS signal is used to control the Push-To-Talk (PTT),

Whee!

Mike If it'll run on Linux, then the Linux-compatibility stuff in
Mike FreeBSD will run it very nicely -- except for a _very_ few
Mike things.

And this is a serial thing, so I'm convinced it'll work just fine --
if it works under Linux.

Thanks for the code segment. I may have asked the wrong question.

Here's another try: can this box do everything a good TNC can do, and
what modifications need to be made to programs that expect a standard
TNC?

It's nothing like a TNC - it's basically just a switch / cable connecter
for use with sound card modem programs. (It tells you that on the web page.)
