Thanks to all the prompt responses (parker@bctm.com, Thad MacMillan, Jose
Montilla, Arthur Darren Dunham), and especially Thad MacMillan for
pointing out the exact technote
(<http://www.livingston.com/tech/technotes/200/220010.html>).
The answer was to escape telnet (Control-]), and type 'send break'.
My original post:
I have a Livingston Portmaster set up to run as the console on a couple of
Sun systems. For those of you who don't know how this is accomplished, I
have a serial cable running from the a port of each Sun system to a serial
port on the Portmaster. Then (as is described at
<http://www.livingston.com/tech/technotes/200/220009.html) I set the
Portmaster up so that I can telnet to a specific port on the PM (i.e.,
'telnet pm 6001') and be connected to the console of the Sun system. From
here, I can log in, bring the system down to the ok prompt, and do all
kinds of firmware stuff. This is a great tool if you have available
Portmasters.
The problem I am having, though, is that I can't figure out how to send
the equivalent of a 'stop-a' through this pseudo-console to the sun
system. If I just do a stop-a, then the machine I am telnetting to the
portmaster from (i.e., my workstation) receives the stop-a. I have tried
various combinations of 'break', because I know that the break key is used
when a terminal is connected to the Sun serial port. As far as I can
tell, Control-break is how I send a break from a Sun keyboard.
So, does anybody have any ideas about how to send one of these systems a
stop-a? I remember reading somewhere about what the ascii code for the
stop-a was, and how to send that code various places, but I can't find the
reference.
Any help with this would be greatly appreciated, as I would like to hook
up most of my servers to Portmasters in this manner.
