- This problem is probably caused by the terminal appearing to send
- a BREAK to the system as it is being powered off or on.
-
- Try one of:
-
- -edit /etc/inittab to specify one of the /etc/gettydefs tags
- that does not cycle among speeds. Try using dx_9600
- instead of co_9600
-
- -edit /etc/inittab to use /dev/ttym1 or /dev/ttyf1 and use the
- appropriate cable, so that when you turn off the terminal,
- the system knows and does not see bogus BREAK's.
-
- -send BREAK's from the terminal to the system until the system
- responds with a login: prompt.
