RS232C Line Control Signals
While the SmartAXIS is in user communication mode, special data registers can be used to enable or disable DSR and DTR control
signal options for port 2 through port 3. The DSR and DTR control signal options cannot be used for port 1.
The RTS signal line of port 2 through port 3 remains on.
In the maintenance communication mode, DSR has no effect and DTR remains on.
Special Data Registers for Port 2 to Port 3 RS232C Line Control Signals
Special data registers D8104 through D8106 are allocated for RS232C line control signals.
Control Signal Status D8104
Special data register D8104 stores a value to show that DSR and DTR are on or off at port 2 through port 3.
The data of D8104 is updated at every END processing.
