We experienced a similar problem recently.  The folks at Telebit gave
us a "fix" -- feed the command  ATJ6S39=3 to your 'blazer... it seems
to make a world of difference.

As Telebit tech support explained, with the 4.0 firmware they
implemented MNP 3 "plus a bit...".  It appears that the "plus a
bit..." is what causes the problems.  The above-referenced commands
cause the blazer to be in true MNP3, rather than the enhanced mode.

As a side note, it has been my experience that the folks at Telebit
are usually able to give a good pointer towards a solution for most
problems we encounter.  It is nice to deal with a company that really
supports what they sell.
