This example runs a stream of ASCII data with software flow control. You must
have a loopback plug installed on the port for this test to pass.

Below is a typical lcom screenshot showing two open channels:

In the example show above, the devices /dev/ttyS0 and /dev/ttyR0 have been opened.
Both ports have loopback connectors attached. /dev/ttyS0 is in terminal mode and
some text has been entered on the keyboard which has been sent and then
received and displayed in the window. /dev/ttyR0 is in throughput mode, and the
test data is seen in the window.
Each window has a status line at the top. The status line may be in place of the
upper window border or immediately below it (as shown above) depending on the
-B command line option. The layout of the status line is:
Dev [Mode]
Dev
is the device name or IP destination. If the device path starts with
'/dev/tty', that portion will not be shown as a space saving measure.
Mode
is the mode in which that port is operating. See modes under the command
line options section.
Flags
is a set of single-character flags that are shown only when they are active.
The flag characters are
Q
Quiet-mode
P
Paused
V
Verify failure
R
Read error
W Write error
E
EOF detected
