Been on the list a few weeks now, trying to figure out where to begin. My first question was about PICs in general and I appreciated the responses I got. But I'm fast learning that I have a lot of ground work to accomplish before I get into PIC's. I think I want to start learning about control using the XT sitting on my desk at home. Maybe write some BASIC to control a stepping motor, then advance to learning about Assembly-type languages. From there, move into the PIC world. So my request for advice is about rudimentary stuff: do you know where I can direct my looking to find out about writing code that uses the parallel or serial port on my XT? If you care to reply, feel free to write me direct, rather than clutter up this good list with something nearly off-subject. Thanks.
