12. Alternate Serial Port Check

port (alternate RS-232C port).

the alternate serial port, then issue the instruction to start the
check.
+-----------------------------------------------------------------+
ALTERNATE SERIAL PORT CHECK
Attach loop-back connector to alternate serial port.
Enter Y to start this check when connector is attachd, or
Enter N to return to the menu.
+-----------------------------------------------------------------+
Since the checking procedure for the alternate serial port is
identical to that for the serial port, its checking procedure is
omitted here.
Only the differences are in port numbers and in the message
titles:
