Use hardware flow control (if it works).

Try turning it on in the modem, and in the driver (FAS?).

Then try downloading then uploading a file using zmodem at both a high
speed and a 2400 baud connection - with the DTE locked at either
19200 or 38400.  If you get a flawless transfer (no errors)
then you should be all set - however - if flow control isn't
working - you will sure enough see errors..
