About BEEP output and input stream

Hi,
 
I have a question about the input and output stream of BEEP. I read the
example on the book, "BEEP", written by Dr. Marshall T. Rose and
published by O'Reilly. There is a client example on page 52:
 
try {
    channel.sendMSG(new StringOutputDataStream(request), reply);
} catch { ....}
 
InputDataStream ds = reply.getNextReply().getDataStream();
InputStream is = ds.getInputStream();
 
while(is.read() != -1) {
    ++replyLength;
} 
 
It uses the message reply object to get the input stream. That means we
have to send a message and wait for the response. This is not what I
want. What I need are two independent threads: one for listening to the
port/messages and one for sending out the message through the port. Is
there any way to have an independent InputStream? Thanks. 
 
Best Regards,
