Other keys are not quite so simple. For example, the
"turned" on and off. When you type

Ctrl
signals are sent to the host device:
This is the way you need to think when encoding
keys requiring a key to be held down while another is pressed. To include
the
keystroke combination in a batch bar code, you would encode
Ctrl+C
$RC$S. For on-screen or serial batch programming for an IBM PC key-
board, you would need to enter (XC1)C(XC0). The ASCII equivalent for

The zap character does not eliminate preambles or postambles.
Including a function key in a bar code can present a problem if your
decoder is programmed to follow every bar code transmission with an
autoterminator character. You can eliminate the autoterminator by includ-
ing the "zap" character, $Z, in any bar code that you do not want followed
by the autoterminator. For example, you would encode %U$A$Z to send
function key
with no autoterminator after it.
