I am trying to execute a Script running a telnet command

Here goes:

What I want to stick into the while loop is if connection
was successful, break... Is there a way I can check whether
telnet connection was successful on each step through the
loop or do I have to restructure my program and try
connecting to a port via fsockopen... By the way
does anyone know what port number telnet connects to...
Telnet is port 23, and the protocol is more complicated than you might
think. Perhaps you could look into using 'expect' (a unix utility) to
control your telnet session. That might bring you less heartache in the
long run.
