I've got the following setup.

* Keyboard, mouse and monitor on Sun Ultra 27. The Ultra 27 has no
serial ports.
* I SSH from the Ultra 27 to a Blade 2000, which has serial ports on
it.
* I use the serial port of the Sun Blade 2000 to set up a Sun Blade
1000.


Ultra 27 $ ssh drkirkby(a)blade 2000
blade 2000 $ tip hardwirea
{OK} boot cdrom.


So I've booted the Blade 1000.

If I screw up, and want to send a break to the Blade 1000, how can I
do it?

You must escape ~

~~#

see man tip

OPTIONS
-v Display commands from the .tiprc file as they are
executed.

USAGE
Typed characters are normally transmitted directly to the
remote machine, which does the echoing as well.

At any time that tip prompts for an argument (for example,
during setup of a file transfer), the line typed may be
edited with the standard erase and kill characters. A null
line in response to a prompt, or an interrupt, aborts the
dialogue and returns you to the remote machine.

Commands
A tilde (~) appearing as the first character of a line is an
escape signal which directs tip to perform some special
action. tip recognizes the following escape sequences:

~^D Drop the connection and exit (you may still
~. be logged in on the remote machine). Note:
If you rlogin and then run tip on the remote
host, you must type ~~. (tilde tilde dot) to
end the tip session. If you type ~. (tilde
dot), it terminates the rlogin.

AFAIK you can't! Break is not a character that you send. I believe the
"break" key sends a "space" signal for two or three character times
before returning to a "mark" signal. You have to hit the "break" key on
a terminal connected to an RS-232C serial port. There is, AFAIK, no way
to do this over the network.

You're being excessively literal. You don't send a break over the network...
you send the control sequence over the network that tells tip to send a
break over the serial line.

This is documented in the tip manpage.

For me I just ^C and it sends a break with no problem.
