I'm having a weird problem with my ST that I was hoping someone on the net
could help me with.  Whenever I call up long-distance bulletin boards, the
following symptoms repeat when I download files or a lot of text is sent to
me at once from the host computer at 1200 baud:

	(1) The connection is fine, and I correctly receive all
	    characters sent.

	(2) Suddenly, I start getting garbage characters instead of the
	    downloaded text.  These garbage characters can be anything from
	    a bunch of 'k's to many percent signs mixed in with random
	    characters.  The characters keep streaming in for
	    a random time (several hundred to a thousand or so
	    characters).  The stream of garbage characters does
	    not stop if the text being downloaded finishes.

	(3) I start receiving the download correctly again (if it is
	    still continuing) for a random amount of time (usually
	    a few hundred characters or so), then get garbage
	    characters again, etc., etc.

This problem does not occur if I connect at 300 baud, or connect to any
local bulletin board.  The long distance bulletin boards I have used are
3000 miles away (San Francisco to the Boston area), and I haven't tried to
call up other places in the US.  I have tried switching modems and using
different terminal-emulator software, but that doesn't seem to help.

It sounds like some buffer in the ST is overflowing somehow, but I wouldn't
have a clue as to what it was or how to fix it.  Does anyone have any
ideas?
