Command Nomenclature
Nomenclature
When describing control codes, confusion often occurs as to whether the command
description is decimal, hexadecimal, or ASCII. To minimize the problem, this
programmer’s guide uses the following nomenclature when describing control code
sequences.
[ ] Encloses a control character. [ ] represents a single, 8-bit value as
defined in the standard ASCII tables. An example would be [ESC],
which would represent a 1BH or 27 decimal.
< > Encloses an 8-bit value in decimal format. The value is from zero to
255. An example is <2>, which represents 02H or 2 decimal.
<xNN> Encloses an 8-bit value in hexadecimal format. The value is from x00 to
xFF. An example is <x12>, which represents 12H or 18 decimal.
<n> Indicates a variable parameter. The variable parameter, <n>, can have
a value from zero to 255. The meaning of <n> is described and defined
in the description of the command.
<n1> <n2> Indicates that there are two parameters, <n1> and <n2>, where both
can have values from zero to 255.
x All other characters in control strings represent ASCII characters. For
e, [ESC] 1 represents 1BH followed by 31H.
