   Not Commodore graphic characters (DesTerm operates in ASCII internally, not 
Commodore codes!)... perhaps PC characters or part of the VT100 line-drawing 
set. These problems have been addressed and will be re-examined as often as 
people come up with concrete problems.

   We haven't heard this one before; what disk drive are you using?

   That's new, too. Do you mean *while* it's scrolling, or that the colour is 
changed by the scroll?

   Grr... Hangup does the following:
 
(1) Drops DTR;
(2) Waits for the Carrier Detect line to go false;
(3) Sends the "modem hangup string" if carrier isn't dropped.
 
   IF (1) you have the modem configured to ignore DTR; (2) the modem doesn't 
indicate Carrier Detect; or (3) you haven't made sure that the hangup string 
matches what the modem interprets as a hangu command, then this feature won't 
work.
 
   I can assure you that this feature, if no other, works fine on properly 
configured systems.
 
 > I was wondering why the file sizes of Kermit 2.2 and Desterm.
 
   ??? - why ... what? I haven't seen Kermit for the 128, so I can't guess 
what its file size is. I'm sure that, if you take a look at what DesTerm does 
(both in terms of various functions and presentation), you'll realize that 
there's a lot being done in there. Except for disk I/O, DesTerm is its own 
operating system, for instance. We don't use the ROM for anything else, 
including:
 
- RS-232 (obviously, if you've seen our baud rate select window);
- Keyboard
- Screen
