Most likely the screen speed isn't the problem.  If you have XON/XOFF
turned on, your speed problems are due to the small RS232 input buffer
in the ST.  If you don't have XON/XOFF turned on, Flash will drop
characters at 9600, and probably at 4800 if your computer can really
send 4800 baud.

The solution is to stick a program in the auto folder that replaces the
I/O buffers with larger buffers.  I wrote a quick little vt52 emulator
(the arrow keys work, and keypad mode almost works), and set the buffers
at 8K each.  The program runs just fine at 19200 - screen I/O is not a
problem.  If you want such an auto-folder program, let me know.  I can
send you source (in MWC), or an executable.

Still, the best solution to your problem I can think of is to get
UniTerm.  This is the program I use now, and it is really good.  You can
get it from the server at Lakesys, I think.
