Ensure that the terminal parameters are set
correctly.
They are:
VT100 / 8 Bits / No Parity / One Stop Bit

Pin 4 & Pin 7 high
Try a selection of baud rates from 300-38,400 and
press Esc-6 after each change.
Hint: If communication was lost during a session, the
system considers the terminal logged-in and will only
respond at the current logged-in speed. Try setting to
the same speed and press Esc-6 (quit) (or Esc-5 from
Maintenance application).
If communication was never established, the system
should respond at any speed.
