    subtype: FrameSubtype

    The specific type of frame being represented (UI, I, SABM, etc.)

    FrameSubtype

    the string name of the frame type.

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

    Whether the frame is an unnumbered, supervisory, or information frame.

    Accessors

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

      Whether the frame is a command frame or a response frame if it is using the latest version of the AX.25 protocol. If not, then it is using the legacy protocol.

      Returns "command" | "response"

      string 'command', 'response', or 'legacy'

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

      Whether the frame is a command frame or a response frame if it is using the latest version of the AX.25 protocol. If not, then it is using the legacy protocol.

      Parameters

      • commandOrResponse: "command" | "response"

      Returns void

      string 'command', 'response', or 'legacy'

    • 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 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 modulo(): 8 | 128

      Determines the number of outstanding information frames allowed per layer 2 connection at one time.

      Only change this to 128 on supervisory and information frames when you are sure that you are using modulo 128, as setting it incorrectly will cause frames not to decode.

      Returns 8 | 128

      8
    • set modulo(modulo: 8 | 128): void

      Determines the number of outstanding information frames allowed per layer 2 connection at one time.

      Only change this to 128 on supervisory and information frames when you are sure that you are using modulo 128, as setting it incorrectly will cause frames not to decode.

      Parameters

      • modulo: 8 | 128

      Returns void

      8
    • 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

      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.

      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.

      Valid values are integers 0 to 255 inclusive.

      Parameters

      Returns void

      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.

    • get pollOrFinal(): boolean

      Used in all types of frames. The P/F bit is also used in a command (poll) mode to request an immediate reply to a frame. The reply to this poll is indicated by setting the response (final) bit in the appropriate frame.

      Returns boolean

    • set pollOrFinal(pollOrFinal: boolean): void

      Used in all types of frames. The P/F bit is also used in a command (poll) mode to request an immediate reply to a frame. The reply to this poll is indicated by setting the response (final) bit in the appropriate frame.

      Parameters

      • pollOrFinal: boolean

      Returns void

    • get receivedSequence(): number | undefined
