My setup is:
PC running a terminal program -> Cable 1.5meters ->
Maxim MAX220CPE -> PIC18F458.

The datasheet says max 120 kbps. Could be they are lying slightly
as suggested =)


The testprogram is from Mchip's Maestro app. that builds small test  programs.
(Program should be ok, but ever1 seems to bitch about mcips's appnotes so... :P)

I cant belive its a software problem like overrund. The datasteam is pretty
slow.
(me type-pic echo)

I'll give that a try.
