   I am contemplating the purchase of some high-speed modems, e.g.,
   Telebit T2500s, and I am uncertain that they will work well with the
   Annex I servers that we have.

I don't think you should have a problem, provided you run a version
of the Annex software that allows you to disable ^S/^Q. If the following
command works at the annex: prompt, you're in luck:

	stty iflow none oflow none

If that's the case, completely disable *all* flow control on the
Telebits. The will increase the modems internal buffer space to the
point where the uucp g protocol will flow control the link before
you run out of resources on the Annex (or the modem).

Caveat: I haven't tried this at 19200 with a Telebit, but I have heard
of others who have done it. The only modems we have on the Annex right
now are 2400 baud.
