I've got a 386/33 with 16650 UARTs, and it gets about 7.3-7.5KB/s through
a 64Kbit ISDN channel (with a 115200 baud connection to the ISDN terminal
adapter). It'll even get that rate on two channels going simultaneously
(to different places; I have one channel to my ISP and the other dialing
direct to work to get behind their firewall).
Do you have any of the PPP compression options enabled? I've noticed that
those tend to slow down the connection if you've got a slow CPU.
