Create serial communication
Devices can communicate with OBLOQ by serial ports RX and TX. Because the baud rate is different, the data sent may be garbled or dropped. The device sends this command to detect whether the device serial port and the OBLOQ serial port have been communicating normally. It is recommended that you check the serial port connection status with this command before communicating with the device.
"|1|1|\r" Indicates that serial communication has been established
