I am attempting to use the "Multiplexing Using Select" Code on page 195 of the Advanced Perl Programming Guide, however, I am unable to see any results from the given code.

I am sending data to the specified port, but nothing is being printed to screen. What am I missing? Am I just completely off?

I am attempting to be able to send data from multiple clients to a single server and have the data sent printed to screen.

Thanks!
