Component/tunnel

Component: Tunnel

This component is provided by the linked card.

This card is similar to the network card's component, but as it is only point-to-point, no ports can be configured, and the connection is always open.

Component name: `tunnel`. Callbacks:

• `send(data...)`

Sends the specified data to the card this one is linked to.

• `maxPacketSize():number`

Gets the maximum packet size (config setting).

• `getChannel():string`

Gets the tunnel address of the link card. This is also available in `linkChannel` using an inventory controller and getting the stack from an inventory slot.

• `getWakeMessage():string`

Gets the current wake-up message. When the network card detects the wake message (a string in the first argument of a network packet), on any port and the machine is off, the machine is started. This is the same functionality also provided by robots, cases, servers, drones, and tablets.

• `setWakeMessage(message: string, [fuzzy: boolean]):string`

Sets the wake-up message to the specified **string**. The message matching can be fuzzy (default is false). A fuzzy match ignores additional trailing arguments in the network packet.

This card generates `modem_message` signals of the same format network cards do.
