Component/abstract bus

Component: Abstract Bus

This card allows for interfacing with [Stargate Tech 2](http://stargatetech.theender.net/miscellaneous/home.html)'s Abstract Bus system.

Component name: `abstract_bus`. Callbacks:

• `getEnabled(): boolean`

Returns whether the local bus interface is enabled.

• `setEnabled(enabled: boolean)`

Sets whether the local bus interface should be enabled

• `getAddress(): number`

Returns the local interface address. `number` is a 16 bit hexadecimal number (0xFFFF being a broadcast).
Returns `0` if an address has not yet been set.

• `setAddress(address: number)`

Sets the local interface address. `number` is a 16bit hexadecimal number.

• `scan(mask: number): table`

Scans the abstract bus for attached devices and returns them in a list.

• `send(address: number, data: table): boolean`

Sends data across the abstract bus. The table `data` is in the form of key-value pairs, e.g.  
```
lua> component.abstract_bus.send(0xFFFF, { ["action"]="dial", ["address"]="Losomdeh Salothirt Erpac" })
```
* See SGTech2 documentation for more info on the Abstract Bus.

• `maxPacketSize(): number`

Returns the maximum size a packet can be sent over the bus.

The abstract bus generates a signal named `bus_message` if a message is received. See the signals reference.
