Thanks Brooke and SJ for the quick  response.

SJ: Unfortunately, I can't use the WinOncore12 program as it runs on
Windows. Recently I shut down my last Windows box and
I am running all Linux.

The problem is that I was using TACC32 Software from CNS Systems
to control my Motorola Receivers and the GPSCon software to control
my HPZ3801A Boxes.

When I tried running these programs using Wine(the Linux Windows emulator)
I had no luck.

So I decided to do a re-write of my older software: "darkgps" to support 
the M12
and the HP stuff. Not a simple task since the Windows programs
are very sophisticated and I want the extra features.

Stuff like plots of receiver parameters, EFC voltages(for the HP units) etc.
are really nice to have. So now,  find myself in the middle of a rather
large software project.

I have access to a 12 channel M12 a few UT units and a few "Basic" units.
The Basic unit was sending out the "Bk" command and I did not know how
to process it.

BTW, if anyone here wants to try out the beta please let me know.
There are two programs, a "c" code shared memory connector
and a perl program that does everything else.

Full source included. I tried to write this one as cleanly as possible 
with plenty
of comments.
