[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0032] In order to solve the technical problems in the prior art that serial port parameter configuration operations for serial port devices are cumbersome and the user experience is poor, the present application provides a virtual serial port parameter configuration method, which can simplify the serial port parameter configuration operation and effectively improve the user experience when performing serial port parameter configuration.

[0033] Figure 1 A flow chart of a serial port parameter configuration method provided in the first method embodiment of the present application, referring to Figure 1 The first method embodiment of the present application provides a method for configuring serial port parameters, which is applied to a host computer and specifically includes the following steps:

[0034] S11: Establish a command channel; wherein the command channel is set between the host computer and the serial port gateway;

[0035] Specifically, a command channel is established between the host computer and the serial port gateway. The command channel is specifically used to transmit the serial port parameter configuration commands on the host computer, and transmit the serial port parameters configured by the user for the virtual serial port on the host computer to the serial port gateway.

[0036] In a feasible embodiment of the present application, establishing a command channel specifically includes the following steps:

[0037] In response to a command channel establishment operation by a user, generating a command channel establishment request;

[0038] Send a command channel establishment request to the listening port set on the serial port gateway;

[0039] In response to the access permission information returned by the serial port gateway, a command channel is established; wherein the access permission information is information generated by the serial port gateway after successfully authenticating the identity of the host computer according to the command channel establishment request.

[0040] Specifically, the user executes a command channel establishment operation on the host computer; the host computer generates a command channel establishment request after detecting that the user is currently executing a command dynamic establishment operation; the host computer sends the command channel establishment request to the listening port set in the serial port gateway, and waits for the serial port gateway's reply; the serial port gateway receives the command channel establishment request through the listening port; after receiving the command channel establishment request, the serial port gateway authenticates the identity of the request object according to the command channel establishment request; after verifying that the identity of the request object is a legitimate host computer, the serial port gateway generates access permission information and returns the access permission information to the host computer; the host computer completes the establishment of the command channel after receiving the access permission information returned by the serial port gateway.

[0041] It should be noted that the command channel is different from the data channel used for data communication between the host computer and the serial port gateway. The command channel does not transmit business data but only transmits serial port parameters. In some possible embodiments, the command channel and the data channel can be distinguished by the difference in communication protocols between the two.

[0042] When the user performs the command channel establishment operation on the host computer, the communication protocol, transmission parameters, transmission mode and other settings of the command channel will be configured, and the host computer will generate a command channel establishment request based on these configurations.

[0043] After receiving the command channel establishment request, the serial port gateway authenticates the command channel establishment request, authenticates the identity of the current request object, and determines whether the current request object is a legitimate request object recognized by the serial port gateway. Only after passing the identity authentication will the serial port gateway allow the host computer to establish a command channel with itself.

[0044] In some possible implementation scenarios, external illegal objects attempt to establish a command channel with the serial port gateway to illegally configure the serial port gateway. Through authentication when the command channel is established, the security of serial port gateway access is effectively improved.

[0045] In a feasible embodiment of the present application, after sending a command channel establishment request to a listening port set on a serial port gateway, the following steps are also included:

[0046] In response to the access rejection information returned by the serial port gateway, a user prompt information is generated to prompt the user to re-execute the command channel establishment operation; wherein the access rejection information is information generated by the serial port gateway after the identity of the host computer is not successfully authenticated according to the command channel establishment request.

[0047] Specifically, if the serial port gateway successfully authenticates the identity of the host computer based on the current command channel establishment request, on the one hand, the serial port gateway will reject the host computer's command channel establishment request, and on the other hand, the serial port gateway returns a user prompt message to the host computer to remind the user that there is currently illegal external access and prompt the user to re-execute the command channel establishment operation.

[0048] S12: In response to the parameter configuration operation of the user, obtaining first serial port parameters corresponding to the parameter configuration operation; wherein the first serial port parameters are serial port parameters of the virtual serial port in the host computer;

[0049] Specifically, when the user configures the first serial port parameters on the host computer (ie, the serial port parameters of the virtual serial port), the first serial port parameters corresponding to the user's parameter configuration operation are obtained. The first serial port parameters include but are not limited to: baud rate, data bit, check bit, stop bit, etc.

[0050] S13: Sending the first serial port parameter to the serial port gateway through the command channel, so that the serial port gateway sets the second serial port parameter according to the first serial port parameter; wherein the second serial port parameter is the serial port parameter of the physical serial port of the serial port device connected to the serial port gateway.

[0051] Specifically, based on obtaining the first serial port parameters, the first serial port parameters are sent to the serial port gateway through the established command channel. After receiving the first serial port parameters, the serial port gateway configures the second serial port parameters (i.e., the serial port parameters of the serial port device connected to the serial port gateway) according to the first serial port parameters.

[0052] In a feasible embodiment of the present application, sending the first serial port parameter to the serial port gateway through the command channel so that the serial port gateway sets the second serial port parameter according to the first serial port parameter includes:

[0053] Generate a parameter configuration command according to the first serial port parameter;

[0054] The parameter configuration command is sent to the serial port gateway through the command channel, so that the serial port gateway sets the second serial port parameters according to the parameter configuration command.

[0055] Specifically, the host computer generates a parameter configuration command based on the first serial port parameter, and the parameter configuration command is used to instruct the serial port gateway to configure the second serial port parameter. The host computer does not directly send the first serial port parameter to the serial port gateway through the command channel, but generates a parameter configuration command based on the first serial port parameter and sends it to the serial port gateway; after receiving the parameter configuration command, the serial port gateway first parses the parameter configuration command, parses the first serial port parameter currently configured on the host computer from the parameter configuration command, and then configures the second serial port parameter according to the first serial port parameter.

[0056] Through the technical solution provided by the above embodiment, the serial port parameters are important data for the serial port configuration. If the serial port parameters are directly transmitted, there is a possibility of being intercepted during the transmission process. By converting the first serial port parameters into parameter configuration commands,

[0057] Figure 2 A flow chart of a serial port parameter configuration method provided in the second method embodiment of the present application, referring to Figure 2 The second method embodiment of the present application provides a method for configuring serial port parameters, which is applied to a serial port gateway and specifically includes the following steps:

[0058] S21: In response to the command channel establishment request, establish a command channel; wherein the command channel is set between the serial port gateway and the host computer;

[0059] Specifically, after receiving the command channel establishment request sent by the host computer, the serial port gateway establishes the command channel.

[0060] In a feasible embodiment of the present application, before the serial port gateway establishes a command channel with the host computer, it is necessary to authenticate the command channel establishment request. The specific authentication method can be any one of identifying the identity carried in the command channel establishment request, decryption authentication based on encryption algorithm, and identity authentication based on account password. The specific method can be freely set by technical personnel according to the actual implementation scenario, and will not be elaborated here.

[0061] After the serial port gateway completes the establishment of the command channel, it enters the waiting state.

[0062] S22: Obtaining first serial port parameters through the command channel; wherein the first serial port parameters are serial port parameters of the virtual serial port in the host computer;

[0063] Specifically, when the serial port gateway receives the first serial port parameter sent by the host computer through the command channel, it ends the waiting state and obtains the first serial port parameter. The first serial port parameter is the current serial port parameter of the virtual serial port on the host computer, which is also the serial port parameter of the virtual serial port configured according to the user's business needs.

[0064] S23: Setting the second serial port parameters according to the first serial port parameters; wherein the second serial port parameters are serial port parameters of the physical serial port of the connected serial port device;

[0065] Specifically, after receiving the first serial port parameters, the serial port gateway configures the second serial port parameters according to the first serial port parameters, where the second serial port parameters are serial port parameters of the physical serial port of the serial port device connected to the serial port gateway.

[0066] In a feasible embodiment of the present application, in order to improve the security of serial port parameter configuration, the host computer will not directly transmit the first serial port parameter to the serial port gateway, but will convert the first serial port parameter into a parameter configuration command and transmit it to the serial port gateway. At this time, the serial port gateway will first parse the parameter configuration command, and then configure the second serial port parameter after parsing to obtain the first serial port parameter.

[0067] In a feasible embodiment of the present application, in order to ensure the efficiency of serial port parameter configuration and avoid the erroneous first serial port parameter affecting the configuration of the second serial port parameter, when setting the second serial port parameter according to the first serial port parameter, the following steps are also included:

[0068] Verify the validity of the first serial port parameter and determine a verification result; wherein the verification result is a parameter validity result or a parameter invalid result;

[0069] If the verification result is a parameter valid result, setting the second serial port parameters according to the first serial port parameters so that the second serial port parameters are the same as the first serial port parameters;

[0070] When the verification result is an invalid parameter result, invalid parameter information is generated and returned to the host computer.

[0071] Specifically, after receiving the first serial port parameters, the serial port gateway needs to verify the validity of the first serial port parameters. If the verification result is a valid parameter result, it can be explained that the user has correctly configured the first serial port parameters and the transmission process in the command channel has not affected the integrity of the first serial port parameters. At this time, it can be considered that the first serial port parameters obtained are valid, and the second serial port parameters set by the first serial port parameters can ensure the correct connection between the virtual serial port and the physical serial port; if the verification result is an invalid parameter result, it can be explained that the user has incorrectly configured the first serial port parameters or the transmission process in the command channel has affected the integrity of the first serial port parameters, resulting in distortion of the first serial port parameters. At this time, it can be considered that the first serial port parameters obtained are invalid, and invalid parameter information is generated, and the invalid parameter information is returned to the host computer to remind the user to verify the correctness of the first serial port parameters.

[0072] In a feasible embodiment of the present application, after setting the second serial port parameter according to the first serial port parameter, the method further includes:

[0073] Establishing a data channel with the host computer according to the second serial port parameters; wherein the data channel is used for data communication with the host computer;

[0074] The second serial port parameters are returned to the host computer through the data channel.

[0075] Specifically, after completing the setting of the second serial port parameters, the first serial port parameters match the second serial port parameters, and the virtual serial port of the host computer and the physical serial port of the serial port device can effectively communicate data through the established data channel. At this time, the second serial port parameters are returned to the host computer through the established protective gear channel, which is used to verify the smooth flow of the data channel on the one hand, and to feedback the setting results of this setting to the user on the other hand, so that the user can know that the serial port parameter configuration is successfully completed.

[0076] Through the technical solution provided by the present application, a command channel is established between the host computer and the serial port gateway. Different from the data channel used to transmit data, the command channel is used to transmit the user's serial port parameter configuration parameters. When the user configures the first serial port parameter on the host computer, the first serial port parameter is transmitted to the serial port gateway through the command channel, so that the serial port gateway configures the second serial port parameter according to the first command parameter. Through the technical solution provided by the present application, the user can complete the configuration of the serial port parameters of the serial port device on the host computer, and the configuration operation of the serial port parameters of the serial port device effectively improves the user experience.

[0077] Reference Figure 3 In a possible implementation of the present application, a serial port software is provided on the host computer, and the serial port software is used to interact with the user. The user can implement operations such as establishing a command channel, configuring a virtual serial port, configuring a physical serial port, and viewing serial port information on the serial port software. The user creates a virtual serial port of the host computer through the serial port software, and the virtual serial port communicates data with the serial port gateway through the data channel. At the same time, a command channel is also established between the serial port gateway and the host computer for transmitting relevant serial port parameters. The serial port gateway is connected to the serial port device through its own physical serial port and the physical serial port on the serial port device. Through the above connection method, a complete communication link can be established between the host computer-serial port gateway-serial port device, thereby realizing data communication from the host computer to the serial port device.

[0078] Reference Figure 4Based on the above connection scheme, the technical solution provided by this application can be implemented in the following way: a virtual serial port management module and serial port software are set on the host computer, and a serial port parameter parsing module is set in the serial port gateway. Among them, the virtual serial port management module of the serial port software provides a serial port parameter configuration interface for the user; the virtual serial port management module is used to respond to the user's serial port parameter configuration operation and intercept the corresponding serial port parameters; the serial port parameter parsing module is used to parse the intercepted serial port parameters and configure the serial port parameters of the serial port device based on the parsing results.

[0079] The overall process of the technical solution provided by the present application is as follows: first, a listening port is established in the serial port parameter parsing module, and a command channel establishment request initiated by the virtual serial port management module is waited for; after the serial port parameter parsing module obtains the command channel establishment request, a command channel is established; after the command channel is established, the serial port parameter parsing module starts to wait for parameter configuration commands; when the user configures the serial port parameters in the serial port software, the virtual serial port management module intercepts the first serial port parameters and generates a parameter configuration command corresponding to the first serial port parameters; the virtual serial port management module sends the parameter configuration command to the waiting serial port parameter parsing module through the established command channel; after receiving the parameter configuration command, the serial port parameter parsing module parses the parameter configuration command and parses out the first serial port parameters; the serial port parameter parsing module configures the second serial port parameters based on the parsed first serial port parameters; after completing the configuration of the second serial port parameters, the serial port parameter parsing module returns the configuration result to the virtual serial port management module and displays it to the user on the serial port software.
