Since I'll be running another headless computer
(HP 9000/380), I brought home
my VT420. Nice terminal, but unfortunately this specimen will only talk, not
listen.
At first, I suspected my HP had lost its settings (the stupid boot PROM must
be set via the keyboard to use a serial console). I proceeded to bring my HIL
keyboard home and set it (without any screen) to use a "remote" console again,
and the machine seemed to acknowledge that, beeping happily. But no response
from the terminal. So I tested it with my DECstation. No response there
either. So I hooked it up to my Amiga. Typing at the keyboard, there was
output in NComm, but doing the opposite didn't work at all.
So we have only one-way communication. What could be the problem?
Is flow control enabled on the terminal? I assume you're using a
DB25 adapter at the other end of an MMJ cable. Try turning off flow
control in the communications setup menu and shorting pins 2-3 on the
connector. At that point the terminal should echo what you type back
to the display. If it doesn't, you might have a toasty RS232 line
receiver in your terminal.
