I'm sorry for asking a question which I know has been asked before but I can't seem to find any way to search the piclist archive nor can I seem to find this information by an AltaVista search. Does anyone know where to get info on both the hardware and software aspects of the Birdirectional PC Parallel port? I am also interested in this info for the ECP and (the other standard, I can't remember the mnemonic for it). BTW It does involve a PIC, it is for the PIC Digital Storage Scope, I just added OT just in case.
