A USER question

[Tom Pancero]

Greetings,

I am in the process of installing a new software package that will be 
integrated in my
Filepro apps.  It will make use of a bi-directional data path to an 
interface program that
handles the communication with the software package using STDIO & STDIN.

System is Red Hat 8 with Filepro 4.8

What method/protocol does the Filepro USER command use to communicate 
with the
'outside world'?

This question is mostly intelectual as I am not having difficulty in 
interfacing the
2 environments but the developer of the software package asked me a 
question that I
did not know the answer to.   KEN, Are you out there??

cheers
