Note: confirmation code = 0x00 Empty success;
Confirmation code = 0x01 received packets wrong;
The confirmation code = 0x11 Empty failed;
command packet checksum (2 bytes) = packet identification (1 byte) + packet length (2 bytes) + script (1 byte);
response packet checksum (2 bytes) = packet identification (1 byte) + packet length (2 bytes) + confirmation code (1 byte);
checksum bytes added to carry more than 2 bytes ignored, big endian transfer;
default module address "0xffffffff"; default password is "0x00000000".
