Max cable length?

[Fredrick]

Update:
9600 Baud and a 15 meter long cat5 cable and it still working whit this code and TTL level signals direct from the PIC.

start:
SEROUT2 lcdtx,84,[254,1]
SEROUT2 lcdtx,84,[254,line1,dec counter," ROW1"]
SEROUT2 lcdtx,84,[254,line2,dec counter," ROW2"]
SEROUT2 lcdtx,84,[254,line3,dec counter," ROW3"]
SEROUT2 lcdtx,84,[254,line4,dec counter," ROW4"]
pause 500
goto start

counter is a long sized variable.

Thanks a lot Frederick, very interesting. This is a good MythBusters episode, at least for me! You want to try another couple speeds, like 19200 and 38,400 (if the LCD has them)? Then you will have some pretty complete info for anyone thinking the same thing!
