有没有办法使用Java通过串口从一台PC发送CRC命令到另一台PC！
这是连接到端口并打开它的代码...
public class Write {
static Enumeration portList;
static CommPortIdentifier portId;
static String messageString = "\n";
static SerialPort serialPort;
static OutputStream outputStream;
public static void main(String[] args) {
portList = CommPortIdentifier.getPortIdentifiers();
while (portList.hasMoreElements()) {
portId = (CommPortIdentifier) portList.nextElement();
if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {
if (portId.getName().equals("COM1")) {
try {
serialPort = (SerialPort) portId.open("Embedded", 8000);
System.out.println("openning the port...");
} catch (PortInUseException e) {
}
try {
outputStream = serialPort.getOutputStream();
System.out.println("sending the command...");
} catch (IOException e) {
}
try {
serialPort.setSerialPortParams(9600,
SerialPort.DATABITS_8,
SerialPort.STOPBITS_1,
SerialPort.PARITY_NONE);
} catch (UnsupportedCommOperationException e) {
}
try {
outputStream.write(messageString.getBytes());
serialPort.close();
} catch (IOException e) {
}
}
}
}
}
