Very cool - been on my wish list for a while!

Cool. Just a thought on this escape sequence... ipmitool and ssh
(amongst others) use ~ after a carriage return as the command sequence,
and this is sort-of a defacto standard...
OpenSSH..
tim@ermintrude:~$ ~?
Supported escape sequences:
~. - terminate connection (and any multiplexed sessions)
[....]
~? - this message
~~ - send the escape character by typing it twice
(Note that escapes are only recognized immediately after newline.)
ipmitool
Special escape sequences are provided to control the SOL session:
~. Terminate connection
~^Z Suspend ipmitool
~^X Suspend ipmitool, but don't
restore tty on restart
~B Send break
~~ Send the escape character by
typing it twice
~? Print the supported escape sequences
Note that escapes are only recognized immediately
after newline.
Both allow you do change the escape character with a command line switch.
Any chance of adopting this "standard" instead of something else?
Any thoughts?
Cheers,
Tim.
