I too had this problem, when trying to connect a VT220 to our 11/750, via a DEC cable we had lying around. Basically, it turns out that lines 0 and 1 respect more of the modem control lines etc. than the others (have a close look at the sockets - they actually have more pins than the others!). Most of the cables we use to connect terminals to serial lines are made by us, and have 9 wires. However, it turned out that the DEC cable we tried to use had only 3 wires (hard to check, as it had moulded plugs), and so was not able to satisfy ports 0 or 1.
