What are DCC packet byte/bit commands for F0-28 in SoundTraxx?

I know the standard packet (byte/bit) structure for calling functions:

OOOOOO11 0 1OO1OOOO 0 EEEEEEEE (F0 - on)

Can someone please tell me the corresponding packet structure for calling F0-F28?

Do you have something (software/hardware) that will let you capture the packets? That should help. I know some tools can listen on the DCC bus. Rocrail has a facility for this. I think there might be some similar feature in JMRI but I haven’t needed it yet.

If you know those then you just aren’t reading dar enough. A few more lines down is the expansion function command. Function Group 1, F0-F is 100, function group 2, F5-F12 is 101, the feature expansion function is 110 with with 11110 being for F13-F20 and 11111 being for F21-F28. Starts around line 285 of the extended packet format standard.
