Restoring non-functional terminals
A completely non-functional terminal displays no
login prompt and does not respond to keyboard input.
This situation is usually caused by hardware failure or
configuration problems. To check a non-functioning terminal:
If this fails to restore the non-functional terminal,
check the terminal's documentation for troubleshooting
Check the brightness control on the terminal.
Check the power and communication connections at the
terminal and computer.
If applicable, enter set-up mode on the terminal and verify
the terminal configuration settings. The settings should
include 9600bps, 8 data bits, 1 stop bit, and no parity.
Enable the port to which the terminal is connected.
For example, to enable tty2a, use the following command:
Verify that there is a getty process associated
with the terminal port. For example, enter:
ps -t tty2a
Test the hardware communications by disabling the port and
redirecting output to the non-functional terminal:
for example, to test tty2a, use the following commands:
echo hello > /dev/tty2a
