Typically, by using the handshaking lines as inputs, rather than the data lines as inputs and outputs, like they should do... Which lead to strange uses and special hardware being the only way to use them as a parallel I/O port. Even for use with a printer, you found you had to fiddle around with BIOS, or other configuration controls, to be able to use some parallel printers, properly, with your computer. In this situation, at least the Amiga did let you use the port as a proper parallel port. 'were the PCs of the day playing annoying games with hobbled ports. I just wish modern computer designers could learn from the mistakes of the past, and not make them again. e.g. Crappy proprietary connectors on old equipment, and copying the mistakes with finicky and fragile connectors on new equipment (miniature firewire ports, dubious plastic SATA ports, etc.). -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
