property RS485Mode : Boolean
Default: False
Determines whether the RTS line should be raised and lowered automatically when transmitting data.
Set this property to True when using an RS-485 board or converter that uses the RTS line to enable the transmit line. In this mode, RTS will be raised whenever the program is transmitting data and lowered at all other times.
Caution: This property should be set to True only when a program is using RS-485 ports or converters and only if those ports or converters use RTS for line control. Enabling this property at other times could cause programs to behave erratically or stop working completely.
Because RS-485 mode requires control over the RTS line, the RTS property is set to False and CTS/RTS hardware flow control is disabled whenever RS485Mode is set to True.
See "RS-485 Support Overview" in the printed documentation for more information on RS-485 support.
