John,

Your post responded to my comment that we had developed two sound card 
modes for the PC. One for windows and one for Linux. Your post only 
indicated:

 "Yes I know I ran test on it....
It was carp.. could only - at best to 42.72 per cent of what a TNC would 
do."

This perhaps was Amtor running under Linux? I don't know the specifics 
of what you were running. Our current reality is that there are ARQ 
modes that run on dedicated boxes that can handle the switching 
requirements (Pactor on amateur radio) and there are ARQ modes that run 
on PC sound cards for Windows (SCAMP tested but not developed further) 
and Linux (PSKmail).

Needless to say, the days of hardware modes is coming to a close 
(hardware to me includes any outboard box even if it has a uP). In fact, 
it is because the sound card modes will not operate the same way as the 
separate box modes, that their availability as a software program will 
change the dynamic. Just as the dynamic was changed irrevocably with the 
initial sound card modes, and particularly PSK31. Almost no one uses 
stand alone hardware boxes for RTTY or PSK31 or any of the many other 
sound card modes anymore. At one time, I had a LOT of money tied up in 
everything from C-64 stuff to later Kantronics and AEA and HAL. Now the 
main depreciating asset is the computer:)

We should not be thinking of coming up with a mode that works with 
Pactor (Amtor is basically long gone for a decade now), but rather, we 
should be thinking of modes that stand on their own and have the 
attributes that have already been proven to work with existing PC's. 
Even faster PC's will make this more and more practical.

73,

Rick, KV9U
