Check how you're handling the EOF signal on Comm, you may be taking it and
closing without sending a NAK. Also, what's the difference between you're
handling of a text and a binary transfer? If you want, upload the source
you have so far to Compuserve and we can all look at it and try to figure
out the problem. That way everybody can look at it and have some rofl.
<grin> Just kidding, also are you using Terminal libraries for this or did
you write all the code yourself?
