stating that a test connector must be in place. The test
connector must have the following pins jumpered: Tx (3)
and Rx (2), RTS (7) and CTS (8), DTR (4) and DSR (6).
This test will only run if the RS232 interface is currently
selected.
A softkey menu offers the following choices:
Run Test - performs the RS232 loop back test and
reports the results.
Cancel Test - quit test and return to previous menu.
