Original Question:
I am in the process of connecting several Sun workstation's
serial 'console' ports up to a Network terminal server. Once
complete this will be great for administration, as I will have
total control over each workstation from anywhere. The only
problem I have (so far) with this setup is that I am unable to
send a 'break' signal to the workstation that is on the
Terminal server (to put it into monitor mode). I am attempting
this from Openwindows on the Console of my server while I am in
an "xterm" window. I would like to know HOW and WHAT "keys" on
the sun keyboard I should map to send a BREAK signal. I have
looked at examples of using 'xmodmap', however I have been
unable to get the desired result. Can anyone help?

Many people suggested something like the following:

>on a Sun, send ~# at the beginning of a line.
I tried this and it works for what I am attempting to do.

Using the telnet 'break' did the trick.

<Key>F2: string(0x1b) string("[4~")
>Insert your favourite BREAK code for the key/string combination you desire.
I didn't try it, however it looks like that would work too!

I haven't tested this YET, however thanks for warning!
