If you've got T2500s, don't even bother with PEP.  Higher level protocols
(TCP) will work smoother over SLIP over a V.32 connection.  If your T2500s
have GA2.00 ROMs, then be sure to run with MNP5 with the serial interface
at 19200.  For the icing on the cake, use Van's recently announced SLIP
w/TCP header compression.

As for PEP w/SLIP; yes, I've run it (although not with a Sun running
SunOS4.0.3).  When rasing the speed link to 19200, be sure all points
(both Suns and both modems) are set to 19200.  Other than that, there
is no inherent impediment with what you want to do.
