Many if not most modems supporting a Hayes-style command set include
several loopback points (digital and analog) which you can turn on via
specific command. Those commands are all non-standardized, so I can't
tell you the commands for yours, but if you can look through a user
manual or command reference you should be able to find them.
Turning on loopback should allow you to do some basic verification
tests, e.g. pipe a file of random binary values into it while
concurrently reading it, and verify that you get the same contents.
Personally, I'd try to get the digital loopback working first, then if
that's OK try the analog loopback point.
