It's certainly possible for two sets of engineers to interpret the
recommendation differently.  It's also possible for one group of
programmers (or both) to make mistakes in their code.

I would expect a problem that really is an incompatibility between
the modems would be easy to demonstrate to tech support.  I can't
think of any data sets that would work fine with Xmodem or Ymodem
but would fail with uucp.  Even so, Telebit tech support has a
Unix system available for uucp testing.  I would suggest that you
call and try some test transfers.  Kermit and X/Ymodem transfers
can be done by any of the support techs.  Uucp can be arranged in
about ten minutes.
