Yes, and I'm not sure why bit doubling needs to be done. It would seem that xmit 0 reversed that is used for "phase encouding" would take care of most of this without all the bit doubling. Having 3 device bytes and 1 command, and then changing that from within the protocol to make 1 device and 4 command bits, so you could take care of that odd sized byte would make a smaller protocol. But I was just trying to adjust some working code.
When we are talking John, is that our John Fine? HE is really clever at writing small code. I haven't seen him arround in a long time. Too bad, because I learned a heck of a lot from him, even though I was of the opinion that he thought I was a lost cause.  |

Thanks Vincy,
The 3 bin files are working. I am new to JP1 and what's the different between the three rmdu? Which one would be the best one to simulate the remote I have? |

Hi Ken,
I was concerned that maybe not having at least one toggle frame was going to make the code less reliable.
For our JP1 remotes, we are looking for one that repeat when held, but for the slingbox, that doesn't matter since you can't hold a key.
Since all of them work, just take the smallest one for the sling.

We tried doing that once upon a time, but this protocol has a double wide bit up front that is required and you can't re-create that by simply sending 0 reversed.

Yup, that's who I'm talking about and yes, he has been AWOL too long!
