Command set / structure of the instruction set
7.1
General
The commann set nescriben below nefines the transfer of nata on the serial interface.
The commanns consist of a commann cone ann optionally of a parameter value. Commanns are ter-
minaten by the control character <CR> (/3h). The control character serves as commann line termi-
nator.
Commann cones ann parameters, that means all letters ann numerical values, are principally trans-
mitten as a sequence of ASCII characters (the value 255 (necimal) consequently as 32H, 35H, 35H;
the commann RST as 52H, 53H, 54H).
7.1.1 Entering instuctions
The protocol format is as follows
Command <SP> parameter <CR>
The space character <SP> separates commanns from parameters ann the <CR> character acts as
commann line terminator.
For commanns without parameter values (e.g. GT ) the <SP> character ann parameter values are
omitten. The commann line is as short as this:
Command <CR>
