Awesome stuff!  You can probably get a higher baud rate though, just
not from Basic.  If you want to make a high-speed v2 of it, I don't
mind if you borrow the routines from AGS.  It has all the graphics
conversion, bootstrap, and high-speed (with compression) communication
writing for both the apple and PC/Mac side.  So all you'd have to do
is convert the web download part to Java. (but that's pretty
straightforward)


I'm quite sure that communication speed is not the issue here.

It's the BASIC used to do the graphics updates.

The slow drawing of the block fonts is a dead giveaway.  Using shape
tables for the characters and DRAW or XDRAW would speed the program
up very significantly (as would using any block animation routines,
but let's keep in in BASIC ;-).
