public class SideBandOutputStream extends OutputStream
This stream is buffered at packet sizes, so the caller doesn't need to wrap it in yet another buffered stream.

public SideBandOutputStream(int chan, int sz, OutputStream os)
chan
- channel number to prefix all packets with, so the remote side
can demultiplex the stream and get back the original data.
Must be in the range [1, 255].sz
- maximum size of a data packet within the stream. The remote
side needs to agree to the packet size to prevent buffer
overflows. Must be in the range [HDR_SIZE + 1, MAX_BUF).os
- stream that the packets are written onto. This stream should
be attached to a SideBandInputStream on the remote side.public void flush() throws IOException
