If I click to set a new serial port or baud rate combobox It suppose to be show me current setting what ever existing and then I have to change.I just want to know how to see existing setting in a cobobox. Please respond my forum.
public String getPortList()
{
return (String) cmbPortList.getSelectedItem();
}
public int getbaudrate()
{

return Integer.parseInt(cmbBaudrate.getSelectedItem().toS tring());
}
public int getstopbits()
{
int stopbits= cmbStop.getSelectedIndex();
switch(stopbits)
{
case 0:
return SerialPort.STOPBITS_1;
// break;

case 1:
return SerialPort.STOPBITS_1_5;
//break;

case 2:
return SerialPort.STOPBITS_2;
// break;

default:
return SerialPort.STOPBITS_1;
// break;
}
}

public int getParity()
{
int parity = cmbParity.getSelectedIndex();
switch (parity)
{
case 0:
return SerialPort.PARITY_NONE;
//break;

case 1:
return SerialPort.PARITY_EVEN;
//break;

case 2:
return SerialPort.PARITY_ODD;
//break;

case 3:
return SerialPort.PARITY_MARK;
//break;

case 4:
return SerialPort.PARITY_SPACE;
//break;

default:
return SerialPort.PARITY_NONE;
//break;

}

}
public int getdatabits()
{
int data= cmbData.getSelectedIndex();
switch (data)
{
case 0:
return SerialPort.DATABITS_5;
// break;

case 1:
return SerialPort.DATABITS_6;
// break;

case 2:
return SerialPort.DATABITS_7;
// break;

case 3:
return SerialPort.DATABITS_8;
// break;

default:
return SerialPort.DATABITS_8;
// break;
}

}
public int getflowcontrol()
{
int flowcontrol = cmbFlowcontrol.getSelectedIndex();
switch(flowcontrol)
{
case 0:
return SerialPort.FLOWCONTROL_NONE;
//break;

case 1:
return SerialPort.FLOWCONTROL_XONXOFF_IN;
//break;

case 2:
