Do make sure that neither modem will recognise X-ON/X-OFF flow control
during uucp as sooner or later an X-OFF char will be sent as part of a
uucp or ack packet and the modem will just stop.

Another point about these modems is they will auto-set the baud rate
*and* *parity* from the first "AT" command they get. Once they think
the're getting even parity they will ignore any odd bytes.  Check that
dial-in modems get setup from a terminal with parity off, and dial-out
ones have a "P_NONE" (or similar) statement in the uucp chat script.
