Is there a way with the standard firmware to receive and
process arbitrary packets, even those wrapped in the standard
Lego IR protocol (as LDCCIRP is)? I'm thinking you may need
to use BrickOS for this application.

Guilty as charged, though I'm not saying exactly how many can be
applied to me... :-)

Undocumented feature: hold down the "beep" key while operating
the speed buttons on the remote control, this will give you finer control
over speed.

Right, CV programming opcodes are on the To Do List.

For the standard headlight, that would be function #0. If your loco
has additional lights, these are activated by the other functions and
are decoder dependant.

With the advent of the LDCC IR Protocol and programs like Full Throttle,
I can extend the number of locos supported by LDCC. The 9 loco limit
is mostly for UI issues with the RCX (i.e. 5 digit display and a few
buttons).

You're welcome! Cheers,

| (...) Argh! Yes, you are right. I was asumimg that since the standard firmware can send arbitrary packets (that is right, isn't it?), it ought to be able to receive them as well. Time to consider alternate firmware. (21 years ago, 6-Sep-03, to lugnet.trains)
