The Fox Message Test

causes a continuous fox

message to be output to the test port. The port that
is being tested will not be able to accept any other
instructions as long as the test continues. The
following will appear on your screen:

The fox message will not echo back to your screen,
but you will not be able to perform any other
functions until the test is terminated. Terminate
the test by pressing or ^X^Y. After you
terminate the fox-message test, you will be returned
to the Command Facility main menu.

The Input Test

sends data input from the

Command Facility terminal to the port to be tested.
During the test, the following will be displayed on
the Command Facility Screen:

Enter some data. The data will be forwarded to the
test channel and echoed back to the Command
Facility screen (your terminal). Neither the
Command Facility terminal or the tested device can
perform any non-test functions while the test is
active.

This test continues until it is terminated (by
pressing or ^X^Y). You will be returned
to the Command Facility main menu. OUTPUT
DATA TEST COMPLETE
