In other words, you can use a similar addxxxliStener such a method for a serial port registration of their own listeners, listening to the data read.To monitor the port, you must first obtain an instance of the Commportidentifier class,Commport SerialPort = Portid.open ("My App", 60); To get Seri

Questions:From there I can learn the basics of serial communication Answer:The basic concept of serial communication 1, what is the serial port. 2, what is RS-232. 3, what is RS-422. 4, what is RS-485. 5, what is a handshake. 1, what is the

What I want to do is a serial port tool similar to a Super Terminal for AT command applications. The option card interface sends at commands to communicate with the data card, facilitating R D personnel to read and write data cards and testers to test, improve work efficiency.Start with two images:When receiving this task, we must first analyze the two main parts of the software. What are the main technical difficulties? The software includes two par

data. Otherwise, data cannot be read and written normally. 5. Read/write row data When both parties communicate, they generally need to define the communication protocol, even though the simplest program that sends text chat through the serial port. Generally, when one party presses the carriage return, it sends the text of the data together with the line break to the other party. In this

program design methods. This paper describes how to use the Win32 API to realize serial communication program in VC + + 6.0 with an example. Implementation principle The example of this paper comes from a cement delivery system, in which the warehouse weights collected through the total sensor need to be passed into t

%. 1th Cable for shielding cable, model for the decp.no.9107723 has three pairs of twisted-pair, each pair of 22# AWG composed of, and covered with shielding net. The 2nd cable is a cable with no shielding. The model for DECP.NO.9105856-04 is a 22#AWG four-conductor cable. 1.rs-232-c is a serial physical interface standard developed by the American Electronics Association EIA (Electronic Industry Association). RS is the English "recommended standard"

nwantread bytes can be read at a time. 4.Event-driven Mode If you have strict response time requirements for port data, you can use the event-driven method. Event-driven mode: sets Event Notifications. When a desired event occurs, Windows sends a notification that the event has occurred. Windows defines the serial communication events in 9, which are commonly used in the following three: Ev_rxc

cannot use the serial port. Getportopen: gets the serial port status. Getinbuffercount: number of characters received in the input buffer. Setinputlen: number of characters that read the input buffer at a time. When it is set to 0, the program will read all the characters in the buffer zone. Getinput: Read the input buffer. Getoutbuffercount: number of characters to be sent in the output buffer. Setoutput:

is specified when the handle is called CreateFile. The operations that call ReadFile and WriteFile on the handle should be overlapping, and the read and write operations should be synchronous if no overlapping flags are specified. The synchronization or asynchrony of the ReadFile and WriteFile functions should be consistent with the CreateFile function.You should use the Clearcommerror function to clear the error before you use the ReadFile function for read operations. The Clearcommerror funct
