step S10, sequentially sending response requests to the external terminals at different baud rates until receiving feedback information sent by all the external terminals according to the response requests;
specifically, the external terminal may be a television, a sound box, a game handle, a set-top box, or the like, the communication device is provided with a plurality of serial ports, and each serial port is connected with the external device through an external data line or directly through a pin, so that high and low level signal transmission can be performed between the external device and the communication device. The invention does not limit the physical structure of each serial port, and does not limit the way in which the external equipment and the communication equipment are connected.
Only if the baud rate of the response request sent by the communication equipment is the same as that of the communication protocol executed by the external equipment, the external equipment can receive the correct response request and generate feedback information according to the response request. Taking an external terminal and communication equipment as an example, the communication equipment sends a response request to the external terminal at a baud rate A, if feedback information sent by the external terminal is not received within a preset time, the communication equipment sends the response request to the external terminal again at the baud rate B until a baud rate n is sent, and receives the feedback information sent by the external equipment within the preset time, so that the communication protocol executed by the external equipment is proved to be data transmission at the baud rate n. The baud rates a and b. The baud rates a and b.

After the communication equipment is powered off, when the communication equipment is powered on again, the baud rate stored in the flash memory and the identification information of the associated external terminal can still be read.
In another embodiment, the baud rate corresponding to the feedback information, the identification information of the external terminal, and the serial port connected to the external terminal are associated, so that after the communication device is powered off, when the communication device is powered on again, the baud rate corresponding to the serial port and the external terminal which may be connected can still be known by reading the association relation stored in the flash memory.
Step S30, receiving the communication information sent by the information sending end, and determining the information receiving end for receiving the communication information according to the communication information; the information sending terminal and the information receiving terminal are the external terminals;
the information sending end can be any one of a plurality of external devices connected with the communication device, and correspondingly, the information receiving end is any one of the plurality of external devices except the external device of the information sending end. The information receiving end determined by the communication information may be specifically one or more.
Step S40, sending the communication information to the information receiving end at the baud rate associated with the information receiving end.
Because the baud rates of the communication protocols respectively executed by the information sending end and the information receiving end are different, the communication equipment is required to set the same baud rate as that of the information sending end so as to receive the communication information, simultaneously convert the communication information, and send the communication information to the information receiving end at the same baud rate as that of the information receiving end.
In the invention, the normal communication can be carried out between the external devices with different baud rates by the device communication method, thereby improving the universality and the connectivity of each external device; the normal communication between two or more external devices can be realized only by connecting the communication device using the device communication method with the two or more external devices, and the structure of the external devices is not required to be changed, so that the use cost is reduced.
