UNIX for Dummies Questions & Answers

Newbie question:
I wrote korn shell script that lets me connect to a cisco switch thru telnet from sun server. I'm wodering if or what command i would use to capture info that is being sent to standard output when the script is running. Putting part of my script below and results.
#!/bin/ksh
hostn='x.x.x.x xxx'
(echo open $hostname
sleep 1
echo "\r"
sleep 1
echo "\r"
sleep 2
echo "dir disk0:\r"
sleep 1
echo "\r"
sleep 2
) | telnet
exit

Results:

rommon >
rommon >
rommon > dir disk0:
file A
file B
rommon >

Connection closed by foreign host.

What i'm trying to do is capture the files A or B and echo that back into the script. Or if i start booting it up i want to capture an error message in real time. Any ideas would be greatly appreciated. Thanks

You may find that a co-process give you better control, and allow you to do as you wish with the responses.

Could you show me an example? Thanks
