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

The following is an example of Z-tek (USB2.0) to a serial adapter (model ZK-U03-2A): 1, according to the requirements of the installation of the adapter driver, "Device Manager/Port", you can find a "USB serial Port (COM4)", the following figure: 2, right click on "USB

the original events. developers can directly The following functions are called to trigger events. These events are loaded by default when the software platform starts. 1) void OnReceiveDataHandler (byte [] revdata ); Trigger receiving data events 2) void OnSendDataHandler (byte [] senddata ); Trigger the data sending event. When the Self mode is applied during network communication, you can use this event to independently send data. 3) void OnDeviceRuningLogHandler (stringstatetext ); Output

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

(unsupportedcommoperationexception e ){}Try {Outputstream. Write (messagestring. getbytes ());} Catch (ioexception e ){}}}}}} The preceding two routines are simplified. After the port is opened and the data stream and serial port are not closed after the transmission is complete. In the routine, we can see that comatrix ortidentifier provides the Open Method to
