Validate a sequence string based on the following format:
Commands (e.g. R0) are defined by a code (R) and an argument (0).
The commands are:
D: setDTR - 1=True / 0=False
R: setRTS - 1=True / 0=False
W: Wait (time delay) - positive integer number (miliseconds)
Sequence string to validate
Is the sequence string valid ?
