Auto Send Data Mode
The IC-485AI operaties in RS-485 Auto Send Data Mode
when SW7 is set to OFF, and SW8 is set to ON.
In this mode, the status of the bus line is auto-detected in
order to prevent more than one signal on the line.
If the the bus line is busy, CTS is pulled high, and the IC-
485AI will not send data to the bus line.
If the bus line is determined to be idle, CTS is pulled low
and the IC-485AI sends data to the bus line.
