The following data bytes are transmitted:
 Serial No. byte 1
 Serial No. byte 2
 Serial No. byte 3
 Serial No. byte 4
 Serial No. byte 5
 Serial No. byte 6
 MSB holding register address
 LSB holding register address
 Number of MSB addresses to be written
 Number of LSB addresses to be written

0x03: - The number of maximum possible registers has been exceeded,
i.e. either more than 123 holding register data or 0 holding register data were defined.
- Byte count ≠ 2 * number of registers
