Re: Problems with solving 0xA5 (time request after power off)

THank you very much Dave, unfortunately i also proved to write only
0x9B but it gets locked, as always. If you could show me a piece of
code i would be most grateful. Incidentally, where can i get some
specifications about CM11G? It seems having the same features as the
other ones.

This is the code i have, in java:

 //data available in serial port
 if( entrada.available() > 0 )
	            {
		            int nBytes = entrada.read( bufferLectura );
                            for(int i=0;nBytes>i;i++)
		            	System.out.println("Got byte " + i + "="+
(bufferLectura[i]&0xff));
                            puertoSerie.close();
		            if(nBytes==1)
                            {
		                Resultado=bufferLectura[0];

		                if((Resultado&0xff)==0xA5)
		                {
		            	  byte tiempo[]=new byte[7];
		            	  tiempo[0]=(byte)(0x9b);
		            	  tiempo[1]=(byte)(0x13);
		            	  tiempo[2]=(byte)(0x40);
		            	  tiempo[3]=(byte)(0x0A);
		            	  tiempo[4]=(byte)(0x48);
		            	  tiempo[5]=(byte)(0x82);
		            	  tiempo[6]=(byte)(0x60);
		            	  for(int i=0;i<6 ;i++)
		            		WriteByteSerialPort(tiempo[i]);
		                }
                            }
                  }
