The DTR control signal option can be used only for the user communication through the RS232C port 1 or port 2.
D8206/D8306 = 0 (system default):
While the OpenNet Controller is running, DTR is on whether the OpenNet Controller is transmitting
or receiving data. While the OpenNet Controller is stopped, DTR remains off. Use this option to indi-
cate the OpenNet Controller operating status.
D8206/D8306 = 1: Whether the
OpenNet Controller is running or stopped, DTR remains off.
D8206/D8306 = 2: While the
OpenNet Controller can receive data, DTR is turned on. While the OpenNet Controller can
not receive data, DTR remains off. Use this option when flow control of receive data is required.

D8207 and D8307 are used to control the RTS (request to send) signal to indicate the OpenNet Controller transmission sta-
tus or operating status.
