Sending control codes to native program

Hello,

I execute a native application with Runtime.getRuntime().exec(), but the application does not return from proc.waitFor(). I feed the application from stdin. Other applications (e.g. cat) runs fine, so believe I have to terminate the input with a CTRL+D or something like this, but it does not work. How can I send a control code to the process?

I tried:

write('\u0004')

write('\u0003')

But why returns:

write('\u000D');

write('\u000A);

an error in the IDE?

Process proc = Runtime.getRuntime().exec(cmd+"\u0004");

BufferedInputStream bufferedIn = new BufferedInputStream(in);

outStream = new BufferedOutputStream(proc.getOutputStream());

errorStream = new BufferedReader(new InputStreamReader(proc

.getErrorStream()));

inStream = new BufferedReader(new InputStreamReader(proc

.getInputStream()));

int b;

while ((b = bufferedIn.read()) != -1) {

outStream.write(b);

}

proc.waitFor();

Thanks, Karsten
