Alternate Serial Port Check; Dot-Matrix Printer Check - Epson EQUITY Y14499113001 User Manual

Each baud rate is tested in turn, and the display informs you of the
progress of the test. If the port does not become ready correctly, a timeout
error occurs. If any data received does not match the data sent, a verify error
occurs, and the computer reports the transmitted and received data at the
time of the error.
The final test is an echo back check during which the port sends data to
itself at 9600 baud, using various data formats. At the start of the test, you
see these messages:
formats
Current data format: 5 data bits, 1 stop bits,
Current test data is @(J
Once again, if any data received does not match the data sent, a verify
error occurs, and the computer reports the transmitted and received data at
the time of the error.

Alternate Serial Port Check

Use this option to test the functions of an additional serial communica-
tions (RS-232C) port. To perform the test you must insert a special loop-back
connector into the alternate serial port so that the computer can check
individual pins of the port.
This test is identical to the check for the primary serial port. For more
details, refer to the description of the Serial port (RS-232C) check above.
