Expect gives you a separate file handle for communicationg with 
the spawned program, so your STDIN and STDOUT are unchanged.  The spawned
telnets STDIN and STDOUT are connected to the filehandle that Expect->spawn 
returns, so you send a string to telnet by printing to the returned handle.

It would help if you post your code.  It might be just a slight semantical misunderstanding or a wrong regexp.

Yes, I have written a regression testsuite that does something similar.

Hope this helps,
