I'll try a null-modem cable on it first. 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)...
