Try setting S9 and S10 registers to 20.  This may delay the modem's
interpretation of the PEP tones long enough to get a connect.  This
kludge has worked on any number of picky brands.  USR users (as well
as some others) learn quickly to disable VOICE recognition, as their
modems fail to distinguish between the Telebit's electronic PEP tones
and the human voice.

As an aside, Setting S10 to 30 or so (3 seconds) on both ends can be
an effective way of disabling call-waiting.
