A TurboCOM would have been my immediate suggestion, so no joy there then

To be honest, I'm not sure you'd notice the difference between 115k and 128k
anyway; I went through this exercise and was disappointed in the results.
It's pretty much OS dependent anyway; the best solution I eventually came up
with was to bin the serial port TA and bought a LAN based ISDN
gateway/router. Slightly more expensive, but fast to set up, uses ethernet
(well understood and cheap), has no special serial port hardware and just
*works*.
I would sincerely hope that your TA is rate buffered (it should be; bin it
if it ain't) and that your handshaking control is hardware based and
properly functional. If so, then I would have thought it should be pretty
much sufficient for most general needs.
