6 -s<serialport> eg -s/dev/ttyS0 normally necessary
7 -w<repeatdelay> usleep; 0 = no usleep; default is -1 = don't repeat at all
8 -i<iterations> default is 0 = infinite; -1 means don't repeat
9 *** the above seems wrong; -1 seems to mean infinite
10 -f<fudgedelay> usleep; each character; default is 0 = no usleep

14 to tell decoder 3 to go speed 13 backwards every 10ms for 1000 times, ie 10s
15 (on norway this means it actually happens every 20ms, ie for 20s,
16 which makes it a bit of a fudge really)

33 Example (always the same msg):
34 P> nmra [*<slot>] [<nmra-command [<nmra-args>...]] nmra speed28 3 13 1
35 P> nmra [*<slot>] [=<nmra-bytes>] nmra =0348

37 P> nmra [*<slot>] [_<pic-literal-bytes>] nmra _7f7f00644197
38 in each case *<slot> indicates that the message should be put in
39 the retransmission cycle, and cancels any previous message with the
40 same *<slot>. <slot> may be empty.
42 cancels the relevant retransmission.
