Communication Adapter Test

This test checks the serial port. Before running this test, you
must connect a special RS-232C connector to the serial port.
The connector requires the following settings:
RD and TD shorted
DSR and DTR shorted
CTS and RTS shorted
You can purchase an AT-type loopback connector from most
electronic supply stores. This connector allows the test to send
out and receive the same data for the purpose of the test.
This test checks the serial port for the following parameters:
9600 baud rate
Odd parity
2 stop bits
8-bit data length
This test first performs a reset function to check for all possible
errors. Then it performs a send function followed by a receive.
