Port Loop-back
Test
WINDIAG allows you to select the communication port (1 through 4)
to test. Depending on the type of network (RS-232 or RS-485) and the
port in question, a special loop-back plug is required:
 Ports 1, 2, 4, and 8 (RS-232) use a 9-pin female D-type loop-back
plug (shown in Figure 5-13).

 Ports 3, 5, and 9 (RS-485) use a 9-pin female D-type loop-back plug
(shown in Figure 5-14).

These tests verify the correct operation of the communication interface
on ports COM1 through COM5 and COM8 and COM9.
