Issues receiving in RXTX

Question

I\'ve been using RXTX for about a year now, without too many problems. I just started a new program to interact with a new piece of hardware, so I reused the connect() metho

Answer 1

If anyone is still getting java.io.IOException: Underlying input stream returned zero bytes after you've read your characters using br.readline() for RXTX (even when you are checking first to see if br.readline() == null), just do this simple fix with a try/catch:

String line;
while (true){   
    try{
        line = br.readLine();
    }catch(IOException e){
        System.out.println("No more characters received");
        break;
    }
    //Print the line read
    if (line.length() != 0) 
        System.out.println(line);
}

I've done some searching and it appears that this is the best/easiest way to get around this problem.

EDIT : I take that back. I tried this and still ended up having some problems. I'd recommend working with the raw InputStream directly, and implementing your own read/readLine method using InputStream.read(). That worked for me.
