   Functiondescription:
   
   This Modul sends parameter to the process or to the skm by itself.
   Different Parameter can manage the function to the skm.
   The number pf Parameters is variable and is different from function to function.  
      
   Input parameter description:

   .....

26 PARA20

   
   The Modul sends many parameter to the process skm o.a and works like
   described under funktion and subfunktion
   Not all parameters are used in all funktions
     
   The Parameters are send to SKM with BLOCKTITLE SA.
   
   FUNKTION CANSTART // SUBFUNKTION GM1:
      Funktion like Dokument RB Entry Condition on CAN by AE/EWG Brand from 28.1.03
      - Send "FIRSTSENDMESSAGE" until TOSEND1. 
      - read message from ECU with TOREC1 and compare it with FIRSTREADMESSAGE
      - wait WSEND2
      - send SECONDSENDMESSAGE with TOSEND2
      - read message from ECU with TOREC2 and compare it with SECONDREADMESSAGE

      The communication starts to SKM with SA and switches to function with "CSGM"
      Rof this the data starts with "U""4"<CSGM>
      The data will be send in format (<FORMATBYTE><LENBYTE><LENBYTEDATA>)*n
      FORMATBYTE: U -> The data ist a unsigned long int
                  S -> The data ist a unsigned short int
                  H -> The data ist a hexstring and will be send in binary
                  A -> The data is a charstring and send as is
