    FrameSubtype

    the string name of the frame type.

    type: "information" | "supervisory" | "unnumbered"

    Accessors

    • get commandOrResponse(): "command" | "response"

      Returns "command" | "response"

    • set commandOrResponse(commandOrResponse: "command" | "response"): void

      Parameters

      • commandOrResponse: "command" | "response"

      Returns void

    • get destinationCallsign(): string

      The destination station's amateur radio callsign. Valid callsigns are 1 to 6 characters (inclusive), all uppercase.

      Returns string

      InvalidCallsignError on frames where this is mutable and an attempt was made to set an invalid callsign.

    • set destinationCallsign(callsign: string): void

      The destination station's amateur radio callsign. Valid callsigns are 1 to 6 characters (inclusive), all uppercase.

      Parameters

      • callsign: string

      Returns void

      InvalidCallsignError on frames where this is mutable and an attempt was made to set an invalid callsign.

    • get destinationCommandBit(): boolean

      Determines in conjunction with the sourceCommandBit if the frame is a command, response, or legacy type frame.

      Returns boolean

    • set destinationCommandBit(value: boolean): void

      Determines in conjunction with the sourceCommandBit if the frame is a command, response, or legacy type frame.

      Parameters

      • value: boolean

      Returns void

    • get destinationSsid(): number

      The destination station's SSID. Valid SSIDs are integers 0 to 15 (inclusive).

      Returns number

      InvalidSsidError on frames where this is mutable and an attempt was made to set an invalid SSID.

    • set destinationSsid(ssid: number): void

      The destination station's SSID. Valid SSIDs are integers 0 to 15 (inclusive).

      Parameters

      • ssid: number

      Returns void

      InvalidSsidError on frames where this is mutable and an attempt was made to set an invalid SSID.

    • get payload(): any

      The data or "body" being carried by the frame.

      Non-objects are stringified then encoded using TextEncoder. Objects are first run though JSON.stringify(), then encoded using TextEncoder. Exceptions are Uint8Array and Uint8ClampedArray objects, which are pushed directly to the payload without transformation. Use this format to transmit raw binary data.

      Returns any

      TypeError if attempting to set a symbol or a Promise as a payload. Symbols are not serializable and promises should be resolved to a value before setting them as the payload.

    • set payload(payload: any): void

      Parameters

      • payload: any

      Returns void

    • get pid(): number | undefined

      Valid values are integers 0 to 255 inclusive.

      Returns number | undefined

      a number corresponding to the layer 3 protocol in use. See AX.25 documentation for a key/value table.

      InvalidPidError on frames where this is mutable and an attempt was made to set the number to a non-integer or an integer that is less than 0 or greater than 255.

    • set pid(pid: number | undefined): void

      A number indicating which layer 3 protocol is in use according to the AX25 spec. Found on information (I) and unnumbered information (UI) frames. Otherwise undefined.
