Has anyone written anything similar to comport for the parallel printer ports? Can anyone point me in the right direction for writing an external that would be able to send and receive data from the parallel ports?
apart from reading and writing to the parallel port it would be interesting to simply set pins of ports. i recently nearly would have needed it for triggering electronics without using a microcontroller. a library can be found here:
http://parapin.sourceforge.net/doc/parapin.html
wrapping it up in an external should be fairly straight-forward. in the document above are links to parallel port faqs that might help you learning more about this port.
the problem is: less and less computers feature a parport as printers are connected via usb or ethernet/wlan. better code fast!
