Transfer Files from Arduino to Casio-FX-CG20

What is the calculator's response to the 0x45 command? Usually you have to wait for a response-Packet (F. i. ACK) after sending a command or a data packet.

Serial.write("56");//checksum(calculated from everything after command)
...wait for ACK
...wait for ACK
I'll be back!
