The ||PPP sounds like a bad ground connection to me.

If he is trying to use a 9 pin port using the commonly available
9-pin cables that a PC uses, it isn't going to work. DEC designed
their 9-pin connector before IBM came out with an incompatible
version, and the IBM version became the standard one.

If you are using a MMJ cable, check the wiring. The two center wires
are ground, and the two bracketing those are the transmit and receive.
The two bracketing those are for flow control, and aren't really
needed if you use xon/xoff.

If you need the pinout, it's in the VT220 manual, among others.
If you can't find it, let me know and I'll look it up.
