We have a Telebit Trailblazer Plus, with a version from ATN?
reported as "GF7.00-TBSA".  It is used for outgoing UUCP and cu,
as well as incoming logins.  We are having a problem wherein
what appears to be buffered data from a previous session is
suddenly dumped into a new session.

As an example, last night I logged into the system from home
using this modem.  This morning, somebody called out from the
system to another system, using the same modem.  After a couple
of minutes of light activity, the modem suddenly dumped a bunch
of text to his screen.  The data that appeared was a copy of the
end of my session last night.  The direction of transmission
was towards the remote system, as it was captured by a vi session
he had running on that system.

This is happening approximately once a week here.  It looks like
something weird is happening with the modem's internal buffers, where
the in/out pointers get messed up and it suddenly retransmits the
entire buffer, or a large portion thereof.  I saw similar problems on
another device (non-modem), which was using ring buffers, and had a
bug in the interrupt handling such that the pointers got into a state
where it looked like the entire buffer needed to be transmitted, and
that's my first guess as to what's going on here.  Has anybody heard
of this problem with TrailBlazers before?  Is there a fix available of
some sort?

Any help will be appreciated!
