NAME
       flush - Flush buffered output for a channel

SYNOPSIS
       flush channelId


DESCRIPTION
       Flushes  any  output that has been buffered for channelId.
       ChannelId must be a channel identifier such as returned by
       a  previous  open or socket command, and it must have been
       opened for writing.  If the channel is  in  blocking  mode
       the  command does not return until all the buffered output
       has been flushed to the channel.  If  the  channel  is  in
       nonblocking  mode,  the  command  may  return  before  all
       buffered output has been flushed; the  remainder  will  be
       flushed  in  the background as fast as the underlying file
       or device is able to absorb it.
