Data that is received by the serial port is normally buffered for a short period
of  time  and  then  forwarded  over  the  Ethernet  to  the  remote  device.  The
VESR4x4  automatically  optimizes  the  data  buffering  to  reduce  the  network
overhead  and  minimize  the  data  transmission  latency.  For  most  applications
the  VESR  will  transmit  data  back  and  forth  seamlessly  between  the  end
devices. However, certain applications may require additional control over this
process. In these cases, the Advanced Port Settings can be used to fine tune
the serial server performance.
