What does the actual application do?  If it is just collecting/logging
data - or even something slightly more complicated you might be able
to replace it with kermit (ckermit package in EPEL) which can work the
same way on serial or tcp connections.

But, I think socat will do what you need if you can make it connect a
PTY (perhaps with optional symlink name) with a TCP4-LISTEN, and have
your application open the pty.
