A function call consists of a length, a function number and the arguments of the function. The
length is calculated by number of the following bytes.
:
Byte ’Length’ + Byte ’function number’ + Number of Bytes ’Argument 0’ up to ’Argument n’
In case a reserved function or a function that is not available is called, the response to this call
is the error function ffh.
