In the table below:

Fis a Final character in
an Escape sequence (F from 48 to 126 in theASCII table)
a control sequence (F from 64 to 126).

Feis a Final character inASCII range 64 to 95.

Gsis a graphic character appearing in strings (Gsranges from
32 to 126) in the ASCIItable.

C0is the set of 7-bit ASCII control characters from 0 to 31.

C1the setof control characters availableonly in8-bit systems.

Ceis a control represented as a single bit combination inthe C1 set
of controls in an 8-bitcharacter set.

Iis an Intermediate character from 32 to47 (inclusive) in the
ASCII table.

Pis a parameter character from 48 to 63 (inclusive) in the ASCII
table.

Pnis a numeric parameter in a control sequence, astring of zero or
more charactersrangingfrom 48to 57 in the ASCII table.
Numericparameters mustbe in decimal radix.

Psis a variable number ofselective parameters ina control sequence
with each selective parameter separatedfrom the other by the code
59 (which usually represents a semicolon); Ps ranges from
48 to 57 and 59.

IBM PC KeyboardReassignment:

Keyboard reassignment uses an undefinedANSI X3.64-1979code sequence
to define a character or set ofcharacters sendby the console whenever
a givenkey is pressed on an IBM PC compatible. The control sequence
is:

ESC [ Pn ; Pn ;... Pn p

or

ESC [ "string" ; p

The first ASCIIcode inthe sequence defines which codeis being mapped.
If the first code is 0 (nul), then the second code is the extended
IBM keycode. The remaining numbers define the sequenceof ASCII codes
generated when this keyis intercepted,or the string (enclosedin
quotes)to be generated. For example:

ESC [65;81pA becomes Q
ESC [0;68;"dir";13pF10 generates dir followed bya CR.
