Ok, let's forget the relay. Instead, what I need help with is using Pin 7 as an output for a device using a serial connector. I've been looking all night, and I don't see any uses of P7 other than for RC boards, AP's or used as in input. I did find out after reading the P7 pitfalls again and again is that the pins 0 thru 5 seem to be constantly powered, so I obviously can't program those either at this point. I just need to know the proper coding for using P7 as a serial connected output - not for sound or RC boards.
This is another attempt at the programming. I really am trying. On a good note; last year I only needed help once. :)
I also don't know why I can't attach the program. The browser can only find the default programs, but here it is in black and white.
Also noted that if I change the DIRS to %10111111 then Pin 7 is constantly powered up as well. Ok, that makes sense, but how do I trigger header pins to operate a device?
Thank you all again.

...and the story continues. A bit of a conundrum here: I put the trainer on the prop 1. It indicates that the header pins are working great so then why is it that when I hook up a serial connector to any of the header pins they are immediately powering up the device? I figured with all of the P7 issues I'd just run from P4, but it won't let me. The trainer however says otherwise. What's going on?
Here's the code again. I configured pin 4 to IsOff immediately, then turn on, but still it remains powered, unless the trainer is on.
I have always used "pin" for the OUT signals, so do I need to use something else for the header pins?
Help me please.

Can you explain, in plain English (no code), exactly what behavior you're looking for? Be very specific. What are you connecting to? This thread seems to have started in the middle which has me very confused.
