Configure Digi devices
Advanced serial settings
The advanced serial settings allow you to 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.
