I am running WinXP SP2, I have disabled the firewall, and allowed the port I
need to use for a program access to the network. If anyone is familiar with
MICROS 3700 POS system using TCP interfacing, it would be great. We have
gotten the program to work only 2 times since the install. I have run telnet
-a and the port is not listed as available. The Micros support eam says only
port 80 and SSl are the only ports not locked. So how do I unlock the port I
need so The micros program can communicate with another server that is
"listening" for my information to come across
 
If you have, as you said, disabled the XP firewall, and if also you
have not third-party firewall and have not used IPsec filtering on
the XP, then your issue is not network availability due to the XP
network stack (since it would be allowing anything).
Tcpview from sysinternals.com could give you a better view of
what is happening on the XP. Your issue may be that the app is
not binding to the ports (due to the app), that the server is not
allowing the communications from/to the XP, or that the network
between is extinguishing the packets.
