KISS Serial TNC

• Connection Name: Display name of the connection
• Auto-start: Automatically start this connection when QTH starts up
• Device: Select the serial device your KISS TNC is connected to
• Baud: Select the baud rate to be used when communicating over the serial port

• Callsign: Override the callsign for this connection. If not specified, the global Callsign selected in Preferences - Station will be used. Please note: If this callsign does not match your licensed callsign, your callsign will be automatically appended to the comment field. This is to both support tactical callsigns and ensure proper on-air identification
• SSID: Enter the SSID of this connection. If not specified, the global SSID in Preferences - Station will be used
• Path Profile: Select a path profile. See Path Profiles for more details.
• TX Delay: Time between keying the radio and sending data, in milliseconds. The default start-up value is 50 (i.e., 500 ms).
• Persistence: The persistence parameter, p, scaled to the range 0 - 255 with the following formula: P = p * 256 - 1. See KISS Protocol for a longer explanation.
• Slot Time: Slot interval in 10 ms units.
• TX Tail: Time to hold up the TX after the FCS has been sent, in 10 ms units. This command is obsolete, and is included here only for compatibility with some existing implementations.
• Fill Duplex: Can this connection transmit and receive simultaneously.
