I have a listener job that accepts incoming requests over TCP/IP and
handshakes (validates)
the connection. A process is then spawned with the give/take
descriptor. It is the latter
process that then has a one-on-one with the specific POS terminal and
sits on a RcvDtaQ.
This program never closes - it is (should) always be ready to accept
incoming requests.

I have worked with many different POS terminals myself. What you are
saying confuses me. You are talking about tcp sockets but the reference
data queues these are two different beasts. In general you have one
server listening then spawn off the connections to the waiting prestart
jobs. When you are finished with the transaction you must close the
connection and return to wait state so the job can process another
request. There is a way and need to signal the listening server job that
the worker job is available again. You also can use multiple threads but
I am not there yet.
