Transmission point
Start codes (STX) and terminal codes (ETX) are automatically added to the data being
transmitted, and the data is transmitted to an external device. (For information on start
and terminal code settings, see section 10.2.)
Executing the
F144 (TRNS)
instruction turns off the transmission completed flag
(R9039).
Duplex transmission is disabled while the
F144 (TRNS)
instruction is being executed.
Check the transmission completed flag (R9039) to determine whether duplex
transmission is possible.
