Note: In Java, the use of Java Communication Package can operate the serial port, But the official package supports the Linux and Solaris platforms after 3.0, and the Windows platform only supports the 2.0 version from 98, but it can be used under XP, and Google can download it. Of course, can also use open source RXTX to achieve serial communication
Pre-preparation of WIN32 serial port programming
1,unzip Javacomm20-win32.zip to c:/.
2,copy C:/commapi/win32com.dll C:/jdk1.4.2/bin
3,copy c:/commapi/javax.comm.properties C:/jdk1.1.6/lib
4,copy C:/commapi/comm.jar C:/jdk1.1.6/lib
5,set classpath=c:/jdk1.1.6/lib/comm.jar;%classpath%
6, if the use of USB port Gsm-modem, you also need to install, usb-to-serial Drive: http://www.jingweigps.com/xzzx.htm (Jingwei Star)
Win32 SMS Modem test steps and at instructions:
1, the installation of USB drive: (http://www.jingweigps.com/xzzx.htm-Jingwei Satellite USB Interface Gsm/gprs Modem driver)
2, open Device Manager to see which COM port is used (display usb-to-serial for COM15), right-click to select Properties, view rate of 115200
3, use Windows HyperTerminal, connect COM15, set rate 115200, other defaults;
4, text-mode test to send SMS

Note 1: If you do not have root permissions, you can execute the following command directly:
Java code Export LD_LIBRARY_PATH=/HOME/APPUSR/JAVACOMM: $LD _library_path export Classpath=.:javacomm_linux.jar: Commons-logging-1.0.4.jar:log4j-1.2.8.jar:junit-3.8.1.jar:mpsp_bs2.jar export LANG=ZH_CN. GBK

List all serial ports and ports of the system to find the serial name used in the SMS modem
Java code public static void showcommports () { commportidentifier portid = null; list port1vector = new vector (; ) list port2vector = new vector (; ) enumeration ports = commportidentifier.getportidentifiers (); while (ports.hasmoreelements ()) { portID = (Commportidentifier) ports.nextelement (); //debug ("commport : " +portID.getName () + " /type: "+portid.getporttype ()); switch (Portid.getporttype ()) { case commportidentifier.port_seriAl : port1vector.add (Portid.getname ()); break; case CommPortIdentifier.PORT_PARALLEL: Port2vector.add (Portid.getname ()); break; default: break;  } } debug ("port_serial = " +port1vector); debug ("port_parallel = " +port2vector); }

Serial port Programming rate test: Use at command to test the serial port rate, high-speed is not compatible with low speed (Send command, return OK means handshake success)
Java code public static void test_rates () throws exception { int[] rates = {2400, 4800, 9600, 19200, 115200, 230400, 460800, 921600, }; com2sms comm = new com2sms (); comm.set_comm_rate (9600); comm.comm_open (5000); for (int i=0; i<rates.length; i++) { try { comm.set_comm_rate (Rates[i]); comm.at_hello (); log.info ("SUCC for rate: "+rates[i]); }catch (exception e) { log.warn ("Fail for rate:" +rates[i]); } sleepmsec (1000, "set_comm_rate:" +rates[i)); } comm.comm_close ( 5000); }
public static void Test_rates () throws Exception {
int[] rates = {2400, 4800, 9600, 19200, 115200, 230400, 460800, 921 ,};
Com2sms comm = new Com2sms ();
Comm.set_comm_rate (9600);
Comm.comm_open (5000);
for (int i=0; i<rates.length; i++) {
try {
comm.set_comm_rate (rates[i]);
Comm.at_hello ();
Log.info ("SUCC for Rate:" +rates[i);
} catch (Exception e) {
Log.warn ("FAIL for rate: +rates[i]");
SLEEPMSEC (1000, "set_comm_rate: +rates[i]");
}
Comm.comm_close (5000);
}
The difference of serial programming under Win32/linux
1, loaded drive names differ (Com.sun.comm.Win32Driver | Com.sun.comm.LinuxDriver)
2,win32 need to load dynamic libraries individually: system.loadlibrary ("win32com")
3, the serial names used are different (COM15 | /DEV/TTYS0), the latter may also require root permissions.
4, the rate may not be the same;
Win32/linux under the serial port programming (shielding platform difference)
Java code com2sms comm = new Com2sms (); Invoke Initdriver initialization Comm.set_comm ("COM16", 115200); Win32//comm.set_comm ("/dev/ttys0", 9600); Linux
Com2sms comm = new Com2sms (); Invoke Initdriver initialization
comm.set_comm ("COM16", 115200); Win32
//comm.set_comm ("/dev/ttys0", 9600); Linux
