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:
RS23X
echo back check - with various data
formats
Current data format: 5 data bits, 1 stop bits,
parity - NONE
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.
Dot-matrix Printer Check
Use this option to check:
l
The operation of your printer in IBM-compatibility mode
l
The compatibility of your printer with the extended character set used
by the Equity I+
l
The ability of your printer to produce bit-image graphics and print
images of the graphics screen.
When you select option 14 from the DEVICE LIST, you see this
prompt:
Is dot-matrix printer on-line (Y/N)?
