of the returned fox message.

be returned to the Command Mode.

the fox message through the remote unit
(Multiserver or feeder mux). The message is
looped back to the terminal that initiated the test.

can be judged by observing the quality of the fox
message (see Figure 12-2). The fox message should
read THE QUICK BROWN FOX JUMPS OVER THE

To end the test, press ^X^Y or <break>. You will
be returned to the Command Mode.
The terminal must be connected to a remote port
