I am looking at building an IR Remote, the plans for which came through sci.electronics a couple of months ago. To make the thing computer controlled, I need to be able to do some TTL I/O from my Mac. In the documentation for the remote, all the examples are for PC/AT type parallel printer ports. I'm trying to figure out if I can rig something up to connect it to my mac. I have a Vanilla MacPlus. I need a simple TTL output and input. I'm willing to jury rig almost anything, although I'd rather not have to break open the mac to do it. If I can just get some kind of TTL I/O from the serial port that would be great. The other question is what kind of software interface will I need to sample and to output the signals? Ideally I would like to be able to run the thing in Hypercard, but I also have Lightspeed Pascal if Hypercard can't hack it. How can I toggle the serial port pins directly, and how can I poll the pins? Any suggestions of solutions or places to look for solutions will be appreciated. E-mail all ideas to me, and I'll post a summary to the net if there is enough interest. -- ****************************************************************************** ** Paul Meyer (602)554-2078 ** ** ** Intel Corp.
