JP1 Remotes

This feature is accessible through the 984 command.

1) Press Setup until 2 blinks
2) Enter 984 (2 blinks)
3) Tap the device button which the punch through will operate
4) Tap any sequence of non-device buttons. These will punch through.
5) Tap any sequence of device buttons. Punchthrough will occur in the selected device modes.
6) Press Setup until 2 blinks

For example, after 984, tap AUD, then Up, Down Left, and Right. Then tap TV, DVR, and CBL. Press Setup until 2 blinks.

Now if in TV, DVR, or CBL mode, tapping Up, Down. Left, or Right will send the IR signals as defined for the arrow buttons in AUD mode. The AUD LED will flash on each tap. However, if the remote is in DVD mode, the arrow buttons will be sent to the DVD device as usual.

Thanks, 3FG. I added your instructions to the wiki, and I uploaded an RDF with the new settings.

I also found that the 971 command followed by a device key sets the value in the low nibble of $21. I haven't discovered any effect from it. Any ideas?

Also, the 974 command toggles bit 0 of byte $2c (reset default=1). I haven't looked for an effect yet.
