  1. Bug fix for the RS485 transmit line being held for a prolonged period after transmission has finished during periods of high SDM line activity with other SDM devices. This sometimes prevents the correct receipt of data from sensors with fast response times, when connected in RS485 half-duplex mode.
  2. Functional change - the Serialflush() instruction from the logger will no longer clear both the transmit and receive buffers. It now only clears the receive buffer. This makes this operation the same as when using the Serialflush command with non-SDM serial ports. This change can prevent transmissions of data being unexpectedly stopped when Serialflush is used shortly after a Serialout command.
