Build a DMX Scene Channel by Channel

DecaBox can receive RS-232 commands and use them to set specific channels to levels. The syntax looks like this:


XXX is the DMX channel, range [000 512]. Leading zeros are required.
YYY is the channel value, range is [000 255]. Leading zeroes are required.
TTT is the time, in tenths of a second, that the internal crossfade
 engine should take to completely process this command. Range is [0 999] 
 in tenths of a second. 23 -> 2.3 seconds. 999 -> 99.9 seconds.

[cr] is a carriage return.


All DMX output channels may be cleared (set to zero) quickly by sending the command


C for Clear.
