Control Sequences
Control Characters and Control Sequences
The valid control characters are located in the code area below 20H. These are the
characters LF, FF, GS, DLE and ESC. All other control characters are not valid, and are
ignored by the controller.
The valid control characters (with the exception of ESC, GS and DLE) are single character
control commands, and directly start control functions.
ESC, GS and DLE are always the start of a multi-character control command, which consists
of a different number of characters after ESC, GS and DLE. They only perform the
requested command if the complete character string is valid. The whole control string will
be ignored if a wrong (not valid) character is found in the string. The next character is than
interpreted as the start of a new command.
