Bitpattern output
Test run to look at the bitpattern of the Arduino.
Set speed 1 direction 0 of locomotive 3:
<t 1 3 1 0> with answer <T1 1 0>
Debug output from <L> gives:
Slot: Reg Bits
M2: 770 37 1 8F C0 43 E8
1 8F C0 43 E8

(*) 2 is speedstep 1 direction 0
On the scope this looks like this.
Curors are at start and end of packet, trigger is at end of 14 bit preamble:
