Depending on the protocol you choose in Step 2, you must set some or all of the
serial port parameters to have the terminal communicate with a host computer or
serial device in a wired network. The values you set for the terminal’s serial port
parameters must match the values set for the host’s (or other device’s) serial port
parameters.

After you connect the 243X to a host computer or other serial device, you are ready to
configure the serial port parameters on the two devices. The terminal uses a
communications protocol and 

XMODEM

 or 

YMODEM

 to handle data communications

through the serial ports.

You can configure a different communications protocol for each COM port. The
terminal’s built-in file operations use 

XMODEM

 or 

YMODEM

 for file transfer.

Communications protocols determine exactly how data is transmitted between the
terminal and the connected device. Each protocol has parameters you can set, such as
baud rate and parity. Both the terminal and the connected device must use the same
protocol and parameter settings to communicate properly. For help with protocols, see
the Data Communications Reference Manual (Part No. 044737).

Binary protocol has no protocol. Characters are sent and received without being altered.
The Data Link Escape character (DLE) is not inserted before any character, and DLE
characters are not stripped out of the incoming data stream. No protocol characters, such
as EOM or SOM, are added. Binary mode supports CTS/RTS flow control.

You can configure the following serial port parameters:

•

 

Baud rate

•

 

Data bits

•

 

Parity

•

 

Stop bits

•
