 V.32 is a 14.4 kbps max, and only applies to the MODEM, not to the
 comm program.  V.35 is a serial interface, like EIA232 (RS232 in
 the old days), which still would become a COMx to the comm
 program. V.34 is a 28.8kbps MODEM protocol ... again, the comm
 program would not normally affect this.
 First, is it internal or external.  If external, is the computer
 port equipped with a 16550 UART.  Is TM setup to use the 16550?
 To get reliable communication with the 33.6 kbps possible with
 V.34+, you will need a 16550 or better.
 When you connect, the modem PROBABLY reports the connection info
 to your terminal ... look in the "back" buffer (alt-B with
 Telemate) if it scrolls by too quickly, or if it isn't displayed;
 Telemate doesn't bother you with some of that handshaking stuff,
 but does keep it for you to see.
 With some modems, you can get a connect speed higher than your
 port speed.  With others, you cannot.  For optimum performance in
 DOS, with very compressible but uncompressed files, you would need
 115.2 kbps com port speed.  HOWEVER, that doesn't work with MANY
 systems.  I'd strongly suggest using 38.4 kbps settings (you can
 get 3500+ cps at 38.4) until all problems are satisfied, then TRY
 57.6 and see if there is any improvement.
TB>the setup is like this "atm s0 blah blah ^M, at&c1 or sumthing"
>8,1,0
 Your modem docs will have to be checked to determine what should
 be used.  The &C1 looks good, but there are several other
 important parameters with Rockwell or USR command sets.
>rts/cts on. xon/xoff off
 very good
>fifo off.
 not good; unless running DOS on a 60 MHz machine (and not for sure
 even then) the overhead of servicing a non-fifo com port will kill
 you.  Be sure you have a FIFO.  Enable it.
 Any ideas?
