Great. I did something similar with Venix on the Rainbow. I'd suggest
getting kermit working first to get things working and also explore the
speeds to expect. Slirp should be faster than Kermit... and slirp may even
fit into i&d.... but the UARTs on DEC gear in that era weren't always built
for speed, so good luck. I hope you have better luck getting good
performance than i did. 2400 was reliable, 4800 wasn't on venix on the
Rainbow (though MS-DOS could do 4800)...

Thanks!

It's communication port is DCE. And the printer is DTE.
What are you connecting?
Wiring up to a Linux box. Going to do some SLIP experiments with Venix.
Anything special about the wiring required?
the basement. At least that's what I use for
connecting it to my FreeBSD
system. You'll likely need hardware flow control signals too and config.
But
I've not used the Pro, but Venix has a
special serial driver. And i
thought
Venix didn't have TCP/IP.
It doesn't, this is a user-mode experiment I'm working on (a very basic
stack
for Venix/PRO through Slirp). I'll try a null-modem cable on it first.
