    Hi,

    I have a PDA Asus636.
    I want to make a small program, in basic4ppc, which is capable to check the state of a relay or a switch.
    My questions are, how to use the pins of the connector and how to check the state in the program.

    Long time ago, on my old 8086 computer, I used two pins of the parallel port. When connected, an interruption is generated. In the software, I modified the interruption routine to set a flag, which I used in the main program. I want, if possible, something similar on my asus.

    Perhaps the projects on my website might be of some use to you.
    I'm still working on a USB connected 'thingy' ;)
