and the last two lines of the LCD
become status lines with a variety of
dynamic information:
The first time you press STATUS,
you see these two status lines. They
tell you the location of the cursor in
the buffer—in this example, the
cursor is at the fifty-first character—
and the total size, in bytes—here 103
bytes of data in the buffer. It also
displays the current byte (the one
the cursor is on) in the following
codes: binary (101001), decimal
(83), and hexadecimal (53).
Pressing STATUS a second time also
shows the current location of the
cursor in the buffer and the amount
of data in the buffer, but further

new data; the screen displays data
already captured: Once again, you
see the current location of the
cursor in the buffer, the amount of
data in the buffer, and the state of
six modem control signals—"hi"
equals high and "lo" equals low—
when that particular byte was
captured.
If you press STATUS a fourth time
you return to a regular data screen
(no status lines at the bottom).
