S-Registers
C-12
Register: S5
Description: This S-register stores the ASCII value for the
backspace character.
Range of Values: Value may be 000 through 032 and 127; factory-default
value is 008, usually output by the key of
the data terminal.
Storable: no
Comments: The operation of the backspace character is to move
the cursor left one character space and (on a command
line) erase the character moved to. If command echo is
enabled (AT command E1), the output of the backspace
character is actually three characters: backspace,
space, backspace.
