I don't really know if a 386 can keep up with a 28.8 modem or not, but I
thought it might be worth mentioning that even though the modem-to-modem
connection is only 28.8 kbps, the serial port connection between the modem
and the computer needs to run at a higher rate, due mainly to hardware
compression by the modem. I doubt a serial port can really keep up with a
28.8 modem if it is running at anything less than 115,200 baud.
