Are you familiar with 'screen'? It's a bitch to google for help on the
damn program, on account of the pedestrian name, but including the
string 'screenrc' (the config file name) often helps. One hint: if
you're use Ctrl-A a lot, e.g. in emacs or readline etc., bind screen's
escape key to something else, like ctrl-T, by appending the following
the /etc/screenrc (or ~/.screenrc, as you see fit):
escape ^Tt
I've been known to use netcat to upload text to cisco devices.
Something like:
netcat hostname 23 < script.txt
where script.txt looks like:
password
term len 0
sho mac-address-table
exit
I know I'm not answering your original question; just thought I'd add
further confusion by introducing even more options... ;)
