No-protocol Mode is used to send and receive data using the communications
port TXD(236) and RXD(235) I/O instructions in the Coordinator Module lad-
der program, without using retry processing, data conversion, branch pro-
cessing based on received data, or other communications procedures and
without converting the data.
No-protocol mode can be used with the RS-232C and RS-422A ports in the
Coordinator Module. Data can be sent or received in one direction only
between the Module and the general-purpose external device connected to
the RS-232C or RS-422A port.
For example, data can be input from a bar code reader or output to a printer,
or parameter data can be sent and received from a host controller.
