That certainly points in a different direction.  One possibility is
that you're running into flow control problems or transparency issues
with the modems.

If they're like USR modems, then "AT&F1" usually does the trick.  If
they're not, then see the manual.  :-/

Two things to try: "asyncmap 0xa0000" and "noasyncmap".  The former
will escape XON/XOFF characters, on the theory that the modems are
eating those characters by default.  The latter will escape all
control characters.
