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.
