Overview<br />
2. Overview of the Implemented Commands and Parameters<br />
The two following tables give a complete summary of all bytes implemented until now and the parameters<br />
given back by the module. The individual designations of the commands and parameters will not be explained<br />
in detail in the tables in favour of the clarity. The descriptions of the used expressions can be taken from the<br />
following chapters in which the individual commands will be described.<br />
The value ranges of the parameters cover all possible entries which are evaluated correctly by the software.<br />
Here it has to be noted that partly special functions (e.g. 'function switched off') have been allocated to<br />
individual values of the parameters (e.g. $00). The allocation of values which are outside of the given limits<br />
is not permissible, because otherwise the perfect function of the addressed module will not be guaranteed<br />
anymore.<br />
