Work with the ASCII table
Sometimes, you might need to send some
control characters that can’t be typed, or
enter characters without a keyboard. You can
do it using ASCII codes.
In
Appendix B
, you'll find the ASCII table. Both
column and row numbers are hexadecimal.
The ASCII code of a character is the
combination of a column and a row number,
where the column comes first. For example,
the ASCII code of BEL is "07" and the number
sign (#) is "23." You can use the bar codes in
Appendix D
to scan ASCII codes.
