• By default the batch mode is off and the sending buffer is flushed at every sending operation of data and command.
• The batch mode is set by "ox_batch" switch of "ctrl".
• If one wants to send many pieces of small data, ctrl("ox_batch",1) may decrease the overhead of flush operations. Of course, one has to call ox_flush(id) at the end of the sending operations.
• Functions such as ox_pop_cmo and ox_pop_local enter a waiting mode immediately after sending a command. These functions always flush the sending buffer.
