    I tried the parallel port conection with ktl 0.3.7, outputs d0-d7 work, but inverted.
    And inputs doesn't look to work, some of them are at high level as espected, but when i drive some to low in the real parallel port, nothing happens in Ktechlab.

    Any help with this?

    Greetings.

    In ktechlab's source you can find in /src/electronics/port.h and .cpp the implementation.

    As I see, reading and writing is done by calling ioctl on the device.

    I don't know if setting the voltage on the port and seeing the change in ktchlab should work or not, but in my opinion it shouldn't be a something very complicated to do.

    ( and yes, you should join the mailing list :) )
