= Port number (01-99).
X1&
= Time in tens of milliseconds that the MGP will wait until receipt of the first response character before terminating the command. (Default = 10 = 10 ms; max. = 32767.)
X2)
= Time in tens of milliseconds that the MGP will wait between characters being received via a serial port before terminating the current command or receive operation.
(Default = 20 = 20 ms; max. = 32767.)
X2!
= #L or #D. The letter parameter is case sensitive (requires capital D or capital L).
L = Length of the message to be received.
D = Delimiter value. A delimiter of ASCII 0A = 10D.
# = Byte count (for L) or a single ASCII character expressed in decimal form (for D).
Byte count # can be 0 - 32767; default = 0. The ASCII decimal # can be 0 - 00255; default = the byte count. A 3-byte length = 3L.
The response includes leading zeros.
X@
= Command data section. For Web encoding for
X@
, be sure to convert non-alphanumeric characters to hex numbers.
