ultra serial port monitor

1 Product 2. Features The main function of this product is to monitor the communication data in the serial line. It is very suitable for serial programming staff. By capturing the serial communication data, we can analyze the communication protocols or data of hardware and software, the biggest advantage of this prod

the receiver, and the effect is clear at a glance. For example: After installing vspm, click vspm-> virtual serial port plug-in the Start menu, and overwrite the vspm. ini file in the directory to the program root directory. Remember to back up the original file. At this time you start vspm again, is the state of COM3-COM4 connection, COM5-COM6 connection. Run two uartassist commands, set them to com

Do not often contact computer friends may be a lot of small computer knowledge do not understand, today's editor in the QQ group of computer enthusiasts have found a friend asked a relatively simple, but the novice friends generally do not pay attention to the problem: what is a serial disk, what is the same port hard drive. Whichever speed is faster and so on. The author found that a lot of friends do not

How do you want to buy a computer or assemble a computer, you first need to know some hardware knowledge, in this article for you to specifically introduce the serial port and the hard disk, and the difference between the two. I hope to help you. In order to facilitate understanding, you can understand the difference between the serial and the hard drives: Coll

Keywords: Java serial port programming, SMS Modem, AT command Ultimate Goal: provide a stable and reliable Java SMS sending server in Linux. Stage 1: Coding and testing on the Win32 platform; Stage 2: deploy and test on the Linux platform; Directory: Related Resources: (Java Communication package) Preparation for Win32 serial Programming Test procedure and

and cannot predict when it will end. In VB program, this problem can be solved by inserting a doevent statement in the loop structure. In Java, the best way is to use threads, just like the following code fragment. Public Testport Extend Thread { ... InputStream input = Serialport.getinputstream (); StringBuffer buf = new StringBuffer (); Boolean stopped = false; ... public void Run () { try { while (!stopped) int ch = input.read (); if (ch== ' q ' | | ch== ' q ') { /* End read,

writetotaltimeoutconstant;} Commtimeouts, * lpcommtimeouts; Set the timeout function to setcommtimeouts. In its prototype, the pointer to receive commtimeouts is a parameter: Bool setcommtimeouts (Handle hfile, // handle to communications deviceLpcommtimeouts // pointer to comm time-out Structure); The following procedure sets the serial port read operation timeout to 10

language) to implement the quasi-Communication Letter Number _ p and _ outp.---- Although the number of API functions in Windows is widely used, the complexity is fixed by the complexity, the programming process is divided into the initial string port, configuration string port, ultra-time control system, data transmission, and closed string

Remember to close the port after it is enabled, andThe connection object is the same. It must be closed after it is used. Port. Close ();} Catch (Exception ex){ // Caught exception information MessageBox. Show (ex. Message, " Prompt " );}} 2. If you want to monitor the status of the device in real time, there is a good event. There is a datareceived event

the writefile () function returns (). because the asynchronous mode works normally in a single thread, the only difference is that when writefile () is executed, it may also execute readfile () (depending on the time when the writefile () function is executed ), the table is not listed here. 3. multi-thread comparison: the performance of a single thread is the same. What about multi-thread? The following code uses multithreading. It first creates a read thread to
