These commands apply to any port that uses RS-232 communication: both 1-way (output) and 2-way (bidir
ectional) RS-232 communica
tion.

, convert nonalphanumeric characters to hex numbers. A
space (hex = 20) is encoded as %20. A
plus sign (hex = 2B) is
encoded as %2B.

operation (default = 10 = 100 ms, max. = 32767).
The response includes leading zer

elimiter value.
# = byte count (for L) or a single ASCII character expressed in decimal form (for D). Byte count # can be fr
om 0 to 32767, default = 0. The ASCII decimal delimiter # value can be from 0 to 00255, default = the by
te count.
Examples:
A 3-byte length = 3L. A delimiter of ASCII 0A = 10D.
