Hmmm. Interesting that you would assume I meant Kerry's opponent, when I mentioned brain-dead voters.
I feel like detective Columbo. "I never said she was strangled! Only that she had been murdered!" |

I'll abstain from the political comments... 8)
I need a little clarification on something from Jon's message in the other thread,

bit5: Overrides the subdevice from the selected fixed data to be the no_subdevice value. That's barely ever useful, since no_subdevice is typically done by having RM or KM compute the no_subdevice value for fixed data. But I guess there might be a need for mixing two different devices and having one of those mix a subdevice with no_subdevice. |
Yes but 0=>Overrides sub-device, 1=>allows subdevice |
When bit5=0, does it ignore the sub-device altogether, or does it just use the complement of the specified device?

1) What's the difference? We define having no subdevice (in NEC) as being the same signal as a subdevice equal to 255 minus the device.
2) I don't see any reason for KM to ever clear bit5 of that byte in this combo protocol. I think the four choices end up being 0x20, 0x21, 0xA0 and 0xA1. If a subdevice field is left blank on the setup sheet, KM already knows how to encode that in the fixed data, so it doesn't need to encoded in the hex command. |

I just wanted confirmation of that.

| BTW, I just wanted to confirm that the NEC 2DEV Combo protocol now works correctly in both RM 1.05 and KM 8.28. I've tested both with my NEC 2DEV Combo device. |
