Serial Loopback Test
Purpose: Use the Serial Port Loopback test to verify that the hardware for the RS-232 serial port is
functioning correctly. To run this diagnostic test, you must connect the terminal to a host
computer or other serial device via the communications dock or optical link adapter.
Where Available: Choose the Main Board Menu from the Hardware Diagnostics menu.

Definition: The serial port test begins immediately. If the serial port hardware is functioning
correctly, the terminal displays WAITING and then RECEIVING. The Serial Port
Loopback test uses the serial communications settings that are listed on the bottom half
of the screen.
On the host, you can use a serial communications package to send data to the terminal. If
the terminal is communicating with the host, the data is echoed back. If there is a
problem, an error message appears on the terminal screen. The status information on the
screen is updated every 500 ms. For help with serial port errors, contact your local
Intermec service representative.
