Question for the net:

A housemate has an original Big Blue IBM PC, running at the blazing
speed of 4.77MHz.  We want to use this as a dumb terminal to access
our university workstations.  The university offers 2400 bps service
with MNP level 5, and a 9600 bps or 19200 bps MCN service using DOV
modems.  We'd really like the extra speed if possible.  Is the PC
going to be able to keep up with 19200 bps?  How about 9600 bps?  It
must be at least 5 years since I touched a PC, so I've lost any idea I
may once have had for the speed of these beasts... 

Oh, and if the PC *can't* keep up, what sort of motherboard upgrade
would we need?  10 MHz 8086?  80286?

Thanks for any information,
Jonathan Hardwick, School Of Computer Science, Carnegie Mellon Univ.
