modbus_write_bits - write many bits
int modbus_write_bits(modbus_t *ctx, int
addr, int nb, const uint8_t
* src);
The modbus_write_bits() function shall write the status of the nb
bits (coils) from src at the address addr of the remote device.
The src array must contains bytes set to TRUE or FALSE.
The function uses the Modbus function code 0x0F (force multiple
coils).
The function shall return the number of written bits if successful. Otherwise it
shall return -1 and set errno.
