I get ~7KByte/sec via PPP/NAT on a IIci, if that is any consolation for you
-- yes, there is hope.  ;)

Make sure you are running with hardware handshake enabled, that's "cdtrcts"
in /etc/ppp/options; be sure to make the modem ignore DTR ("AT&D0" modem
command).

Start with slow tty speeds - say, 19k2 - and move up slowly. For a IIcx,
38k4 would probably be enough. Watch "pppstats -w5" for transmission errors.

Disable modem compression, as the modem will likely connect at speeds
higher than your tty speed, anyway.

Good luck,
