Gosh, I'm pleased. My internal documentation was actually clear. :-)
On that note, I was really hoping to work more on this before putting it out
for public consumption, but I am now at the end of the week and I am heading
out of town. When I get back I will re-write the two areas that are Linux-only
to make it Windows compatible. This program is of limited use, though, unless
you have a ProComp. Other devices can easily be added. Also, there is no GUI
output. I will be adding some real-time graphics displays later to continue
testing interface ideas. To me, this program is more of a "playground test
bed" to work out ideas and test assumptions. The fact that it actually does
something useful, like read data from the ProComp is a plus.
Anyway, for those curious, the code can be found here in tar, gzipped format:

The detail that Jim-P refer's to above regarding the ProComp's method of
transmitting data
