Character
Numbering
Character map positions are referred to by the
ASCII decimal numbers 0 - 255 and are desig
-
nated with a trailing d. The programmer will re
-
fer to these character locations using
hexadecimal numbering and are designated as
hexadecimal with a h. See the character map in
Appendix A
for reference.
Basic Command
Syntax
Each command consists of an ESCape (de
-
noted as ¬ or ESC) character followed by a sin
-
gle ASCII character to identify the specific
command desired. Some commands require
one or more additional parameters to complete
the command. Refer to Figure 1-1. for the basic
command syntax.
Each command line must be terminated with a
Line Feed (LF) character. As an alternate
method both the Carriage Return (CR) and Car-
riage Return Line Feed (CR/LF) combination
may be used. Most PC based systems send a
Carriage Return Line Feed (CR/LF) when the
Enter (Return) key is pressed.
