Ehrm... I don't wanna spoil the fun, but for JoyNet, we're talking
about asynchronous communication. What you describe here
("...based upon a fixed time...baudrate") is synchronous comm.

Get real. If you've got 50 MB to transfer, JoyNet is definitely
not the way to get it done. You'd better take a RS232 or similar
type of communication...
[Transmission errors]
>(for games, this might even introduce a nice 'random' element!).
Yeah, right. Then I can't shoot my enemies because they jump around
all the time, due to the transmission errors, instead of staying
nicely where they are :-)
