Below is the setup that I am using with my TB+ on V/AT 2.4. I am also using
a version of uugetty that changes the value in S50 to 255 when I am calling
a system at the higher speed. Also important is to set S92 to 1 which will
cause the system to answer with the PEP tones last so as to not drive the
1200 and 2400 baud modems crazy.

As far as transfer speed goes the second section below shows my system
averages for two days. The sites kd4nc, gatech, and nanovx are running
trailblazers. kd4nc is also a V/AT 2.4 system and nanovx is a Xenix system
and as you can see the best transfers seem to be to nanovx. I'll leave
any conculsions to you.

I am currently running a Trailblazer and 1 hayes 2400 modems. My second
Trailblazer is on the way and the hayes will be put on the shelf with
its mate. I have a Connect Tech 8 port inteligent board and kd4nc is
running their 4 port.  The boards work real well and we havn't had
any problems with them.
