Automated logins and file transfers from a KSh script ?

[Gene Spafford]

If you are using a recent version of ksh, I would suggest you try
something along the following lines:

1) dispatch the cu process as a co-process, ie:
cu -l/dev/ttyAp5 -s2400 |&

2) send it commands with "print -p"

3) Write an "expect" function along the lines of:

function expect
    {
	typeset pattern="$1"
	while read -p response
	do
	    if [[ $response = $pattern ]]
	    then
	        return
	    fi
	done
    }

3)  Call "expect" with ksh style patterns, like 
expect "*connected*"


The coprocess feature of the ksh is a very powerful way of handling
these kinds of situations, but many users don't seem to think to use
it.
