4.1.2 SerialClose
This will place the SDM-SIO1 unit into shutdown mode where only SDM
communications will operate. This means any data coming into the SDM-SIO1 on
the RS-232/RS-485 interface will be lost.
This is the lowest possible power mode and for optimum power efficiency the
SDM-SIO1 should be placed in this mode whenever possible.
