Chapter 3— Operating the Terminal in a Network
Trakker Antares 243X Handheld Terminal User’s Manual 51
Using Serial Communications on the Terminal
The 243X has a serial port to transfer data to and from another device,
such as a printer, modem, or PC, using serial communications. Before you
can use serial communications, you must perform these steps:
1
Connect the terminal to a serial device or network. For help, see
“Connecting to a Serial Device or Network” on page 29.
2 Choose a communications protocol. For help, see the next section,
“Choosing a Communications Protocol.”
3
Configure the serial port parameters to allow the terminal to
communicate with a host computer or serial device in a wired network.
For help configuring the terminal, see Chapter 2, “Configuring the
Terminal.”
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.
Choosing a Communications Protocol
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,
XMODEM1K, 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,
XMODEM1K, 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 (P/N 044737).
Binary Protocol
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.
