How to use java to connect to a mobile phone or SMS cat through a serial port in linux to send a Chinese text message

In linux, you can use java to connect to a mobile phone or SMS cat through a serial port to send a Chinese text message-Linux general technology-Linux programming and kernel information. The following is a detailed description. Download the jar package, decompress it, and copy the so file to/usr/lib.

Copy javax. comm. properties to the jre directory.

Put comm. jar in the classpath directory

Serial port connection:

Commp ortidentifier portID;
String owner = new String ("modem ");
Int keeptime = 5000;
Enumeration portList;
PortList = commp ortidentifier. getPortIdentifiers ();

// String driverName = "com. sun. comm. Win32Driver ";
String driverName = "com. sun. comm. LinuxDriver ";
CommDriver driver = null;

Try {
// System. loadLibrary ("win32com ");

Driver = (CommDriver) Class. forName (driverName). newInstance ();
Driver. initialize ();
System. out. println ("Win32Driver Initialized ");
} Catch (Exception e ){
E. printStackTrace ();
}
// If multiple ports exist
While (portList. hasMoreElements ()){
PortID = (comatrix ortidentifier) portList. nextElement ();
System. out. println ("COM:" + portID. getName ());
// If (portID. getName (). equals ("COM1 "))
If (portID. getName (). equals ("/dev/ttyS0 "))
Try {
SPort = (SerialPort) portID. open (owner, keeptime );
Break;
} Catch (PortInUseException e ){
E. printStackTrace ();
System. exit (1 );
}
}

Try {

If (sPort! = Null)
{
In = sPort. getInputStream ();
Out = sPort. getOutputStream ();

Try {

SPort. addEventListener (this );
SPort. notifyOnDataAvailable (true );
} Catch (TooManyListenersException e ){
E. printStackTrace ();
}
}

} Catch (Exception e)
{
E. printStackTrace ();
}

Note out the connection method in windows.
