We've run SLIP on both a Digiboard 8i and a dumb ASY port with a
16550AFN at speeds of 38400. Throughput on the Digi is higher
than the ASY port.
Throughput averages around 1780 cps running UUCP over SLIP using
v.32bis modems.

yep - we've noticed this when bringing SLIP up and down - thank
goodness we don't go up and down all day long!

yes - for sure
We are planning on moving over to Dell SVR4 3.0 when it is released
for our primary gateway. Dell is constantly working on the product -
and their 2.01 release is quite solid.
The ability to support multiple concurrent SLIP connections is
quite appealing
