X1&
= time in tens of ms for the IPL
T S unit
to wait until r
eceipt of the first r
esponse
character befor
e terminating the curr
ent
receive operation (default = 10 = 100 ms, max. = 32767). The r
esponse includes
leading zer

X2)
= time in tens of ms for the IPL
T S to
wait between characters being r
eceived via
a serial port befor
e terminating the curr
ent
receive operation (default = 2 = 20
ms,
max. = 32767). The r
esponse includes
leading zer

X2!
= #L
or #D. The letter parameter is case
sensitive (r
equir
es a capital “D” or capital
“L”). The r

elimiter value.
# = byte count (for L) or a single

Byte count # can be fr
om 0 to 32767,
default = 0. The
ASCII decimal delimiter #

3-byte length = 3L. A
delimiter of

a) equal zer
