[kaffe] Serial Port on Kaffe

[Josef Nordangård]

It is also possible to open the serial port as a file. Init the port using system calls. A small example for linux:

------------------------
    public Serial(int baudrate, boolean evenparity, int stopbits, 
		  int charsize) throws FileNotFoundException, IOException{

	Runtime rt = Runtime.getRuntime();

	// Sets up the port with specified baudrate, parity, stopbits, 
	// and character size.

	if (evenparity)
	    parity = "-parodd";
	if (stopbits == 2)
	    sbits = "cstopb";

	String cmd = 
	    "settty " + comPath + " " + 
	    baudrate + " " + parity + " " + sbits + " cs" + charsize;
	try {
	    Process p = rt.exec(cmd);
	
	    if ((p.waitFor()) != 0) 
		throw new IOException("Error initzialising serial port");
	} catch (InterruptedException e) {
	    throw new IOException("Error initzialising serial port");
	}

	out = new BufferedWriter(new FileWriter(comPath), 50);
	in = new BufferedReader(new FileReader(comPath), 50);
    }

------------------------

settty is just a small script.

My belief is that you'll need to resort to using JNI to do this.  Sun
has the Java Communications API for Windows but it use JNI.  Maybe
others have insight on the best method.
