These settings adjust the serial port and serial gateway properties.

Baud rate
Select the serial transmission speed ("300" to "115200" Baud).
Default: "9600"

Data bits
Select "7" or "8" data bits.
Default: "8"

Parity
Select "no", "even" or "odd" parity.
Default: "no"

Stop bits
Select "1" or "2" stop bits.
Default: "1"

Flow control
Select the type of flow control: "none", "Software (XON/XOFF)" or "Hardware (RTS/CTS)".
Default: "none"

Local port
Defines the port on which the serial port can be accessed for serial gateway application. Only when "Local port" is set to "0" the serial port can be used as a command interface.
If the active serial gateway is enabled and the "Local port" is set to a value then this will be the source port of the TCP connection. On "0" a random source port is used.
Default: "12303"

Destination IP
To have this device actively establish a serial gateway select the destination IP address to the device where the serial data will be transmitted to (and received from).
Select "0.0.0.0" when the serial port is only used local.
Default: "0.0.0.0" (disabled)

Destination port
Defines the port for the active serial gateway function (see destination IP).
Default: "0" (disabled)

Notes
Both settings, "Destination IP" and "Destination port" have to be set to enable the gateway function.
