Advanced serial settings
The advanced serial settings further define the serial interface, including whether port buffering
(also known as port logging), RTS Toggle, and RCI over Serial are enabled as general serial
interface options. You can also define how specific aspects of TCP and UDP serial
communications should operate, including timeouts and whether a socket ID is sent.
Serial Settings
The Serial Settings part of the page includes these options:
Enable Port Logging: Enables the port-buffering feature, which allows you to monitor

incoming ASCII serial data in log form. The Log Size field specifies the size of the
buffer that contains the log of ASCII serial data.
Enable RTS Toggle: When enabled, the RTS (Request To Send) signal is forced high

(on) when sending data on the serial port.
Enable RCI over Serial (DSR): This choice allows the Digi Connect device to be

configured through the serial port using the RCI protocol. See the RCI specification in
the Digi Connect Integration Kit for further details.
RCI over Serial uses the DSR (Data Set Ready) serial signal. Verify that the serial port is
not configured for autoconnect, modem emulation, or any other application which is
dependent on DSR state changes.
