     I've noticed this too.  If you click ok to the error dialog fairly quickly,
the file will transfer okay.  If you wait too long, the last part (sector?)
won't make it.
     (NOTE:  The dialog always comes up at/near the end of the transfer.)
     I have no proof, but I think it happens to me more when all of the
following are true:
	1)  The file is text (macget -u)
	2)  The file is large
	3)  The baud rate is fast (9600).
     (It almost always happens when I upload a 100K-200K PostScript file
to our Vax or Sequent at 9600 baud for eventual LaserWriting.)  (You want to
be quick with the OK box to avoid having to redo the transfer.)

     That's only because it's losing the CR's, not the important stuff.

     I don't think it's a binhex problem.  As I said, it happens to me with
other text files (PostScript files).  I think you're close, though.

> Is there some macget fix that I missed?
     I've applied every macget fix I've seen.  I don't think macget is the
problem either.
************  MY POINT ***************
     Which leads me to the conclusion that it's MacTerminal's fault.  I think
MacTerminal may be screwing up the logical/physical EOF stuff.
     Has anybody done this with pure Mac to Mac transfers?  That would rule
out macget.  If I get a chance, I'll try it myself.

     Or be quick with your OK click.
