I have been remiss in posting the summary for this message but I had problems
with my mail system....
Solution:
The solution that worked for me is attaching a system to serial port A via a
null modem. Below is the solution and other possible avenues that may be used
depending on the circumstances:
----------------------------------
rpae@jgbdev.fi.gs.com (Emy Parparita):
disconnect the keyboard from the ultra and use a dumb terminal connected to
serial port `a' (9600 bauds, 8bits, no parity) and press the hold key or ctrl/s
to stop the display at any point. even better you can use a pc (windos,
terminal app in no modem mode, 9600 bauds, 7 bits, space parity) or a serial
cable from the serial port `b' of a nearby sun, running `tip -9600 /dev/ttyb'
in a xterm. the last two solutions offer you a scrolling window so you can
trace back the messages.
the cables:
pc sun, port a
female 9p male 25p
2 ------------ 2
3 ------------ 3
5 ------------ 7
sun, port b sun, port a
male 25p male 25p
2 ------------ 3
3 ------------ 2
7 ------------ 7
see also `man tip'.

What I do to counter this problem is to boot to single user and then manually
execute each of the scripts, in order, in the /etc/rc*.d directories.

You can try connecting a vt100 terminal Or PC running terminal emulation
program on the serial port of your system and view the error message
That will help in debugging as well

Have you tried the STOP-A keys combination, to stop the process
and see the messages?

bismark@alta.Jpl.Nasa.Gov (Bismark Espinoza):
Look at the files /usr/adm/mess?* .
