ecuting. The original instruction will continue normally; the one
in error will be ignored.

control instruction.
Invalid byte received while parsing a device control instruction.
The parameter containing the invalid byte and all following
parameters are defaulted.
Parameter out of range.
Toomany parameters received. Additional parameters beyond the
proper number are ignored; parsing of the instruction ends when
a colon (normal exit) or the first byte of another instruction is
received (abnormal exit).
