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

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

Steve No. The rigblaster (and the rascal--I own both) are merely
Steve soundcard interfaces. That is, they have transformers to
Steve isolate the audio circuits, and relays to operate the PTT. The
Steve rigblaster is popular for its professional look and
Steve adjustments, while the rascal is popular because it is cheap
Steve and can be thrown behind the table. Both are just audio and
Steve relay devices, and there is no TNC in them. The TNC is the
Steve Linux/FreeBSD computer.

That explains a lot. I understand a little more now. What Unix
software do you use for TNC purposes? I see a bunch of Windows
support, but there's no obvious documentation or example code for Unix
boxes. I have read that the RigBlaster comes with CDs of software,
but there's no specifications out there that I can see.

Steve I haven't messed with TNC's since I ran JNOS on a linux box
Steve (about 10 years ago), and now pretty much have my rascal on my
Steve windows box with either AGWPE for my APRS soundcard interface,
Steve or the various soundcard digital modes (MT63, PSK31, etc). As
Steve a matter of fact I took all my TNC's to a swap meet and sold
Steve the whole box for $5 (and it took about 2 hours to find a
Steve buyer). About the only stuff I have left is a couple of 19k
Steve baud Kantronics Radios and DRSI modems that were crap when they
Steve were new :-)

I'm happy with my PK232 at the moment, but it'd be nice to lower the
startup cost for packet radio for Unix users.

Jack.
