APC top-level constant

String const APC

Application Program Command.

APC is used as the opening delimiter of a control string for application program use. The command string following may consist of bytes in the range 0x08 to 0x0D and 0x20 to 0x7E. The control string is closed by the terminating delimiter STRING TERMINATOR (ST). The interpretation of the command string depends on the relevant application program.

Implementation

const String APC = '${ESC}_';
