Entering ASCII Control Characters

There are two types of configuration parameters that you can use to enter
ASCII control characters for the settings. They are communications protocol
characters, and operation preambles and postambles.

Communications Protocol Characters

Some communications protocols require you to set the protocol character to an
ASCII control character. To enter an ASCII control character for one of the
protocol characters in the dialog box, such as EOR and EOM, press c followed
by a letter, number, or symbol key. For example, to enter the ASCII character
STX, press c B and the word <STX> appears in the protocol character field.
The ASCII control characters and their corresponding keys are listed in
Appendix A.
If you want to disable the protocol character, highlight the space next to the
protocol character you want to disable and press b .

Operation Preambles and Postambles

You can include ASCII control characters in the preamble or postamble fields
in the dialog box using an escape sequence. For example, to set the postamble
to Carriage Return Line Feed, enter:
\r\n
The escape sequences for the ASCII control characters are listed in Appendix
A. If there is not an abbreviation for the ASCII control character, enter the two-
digit hexadecimal number (\xnn where nn is the hex value) for the ASCII
control character. The hex numbers are listed in the full ASCII chart in
Appendix A. For example, to enter the value for ETX, enter:
\x03
