The disk cache problem only occurs under certain conditions with
HIGH SPEED modems (9600 and above).  I doubt that this is a factor at
2400.  More likely, I would think, that you  have a defective modem or
serial port or (much as I hate to mention it) a line noise problem.
You aren't trying to do these transfers under Windows in the BACKGROUND
are you?  That combo doesn't work very well with most comm. programs
especially on an AT or less.  Come to think of it, I seem to remember that
some comm. programs don't perform well under Windows even in the foreground.
