In the past, I've used dos, Qbasic, and Parallel port to control up to 8 SSRs. (Just by sending 0-255 to the correct I/O address, I can turn on/off pins 2-9.) Anyway, I'd like to convert this DOS box over to FreeBSD so that I can make changes remotely. How difficult would it be to send a byte out to the I/O address of the parallel Port on a FreeBSD box? Secondly, Anybody ever worked on a driver for digital I/O boards? (Like the CYDIO192 board from http://www.cyberresearch.com). From what I can tell, it doesn't seem any more complicated then just sending bytes to the correct I/O port. (I could be very wrong as I'm not good with the hardware level.) Thanks! Greg.
