E1DC Dynamic console selection. If a console is attached but nothing
is displayed on it, follow the steps
associated with "All display
problems" in the Entry MAP tables.
If selection screen(s) can be seen
on the terminals and the appropriate
key on the input device associated
with the disired display or terminal
is pressed, within 60 seconds, but
there is no response to the
keystroke:
1. If selecting the console with a
keyboard attached to the
system, replace the keyboard.
If replacing the keyboard does
not fix the problem, replace the
I/O board. (See notes on 3-1.)
2. If selecting the console with an
ASCII terminal, suspect the
ASCII terminal. Use the
Problem Determination
Procedures for the terminal.
Replace the I/O board if these
procedures do not reveal a
problem. Note: Terminal
