[wplug] Bash Expect usage - Automating telnet

[scoob8000]

ssh isn't an option since these are just low end devices.  They only
support telnet or http.

I can't even get it to spawn the telnet session, I'm sure it's something
simple in my syntax that I'm missing.

Here's what I get:
missing close-bracket while executing "if [catch spawn"
couldn't read file "telnet": no such file or directory

I'll take a look at autoexpect.
