Somehow i think this is just wrong. All telnet clients i have looked at
interact with te controlling terminal (for example by switching into 
raw mode during the password entry ....). The expect solution Daniel posted
does nothing more than attach to a pseudo-terminal and pipe the standard
filehandles to the ptty.
