Also you could use netcat (nc) or socat with appropriate arguments to
conect to the socket and transfer the data to stdout rather than
writing a perl script.
I would not suggest using telnet to do this, it can sort of work but
you will occasional get odd behavior which is less likely with
socat/netcat.
So a spawn command that runs:
nc ip_addr port
will take the data from a tcp socket at ip_addr:port and send it to
stdout (and into SEC).
