All Implemented Interfaces:

Message

public class SpecificMessage
extends SerialMessage

Contains the data payload of a serial packet.

The transmission protocol can come in one of several forms:

• If the interlocked parameter is false (default), the packet is just sent. If the response length is not zero, a reply of that length is expected.
• If the interlocked parameter is true, the transmission will require a CRC interlock, which will be automatically added. (Design note: this is done to make sure that the messages remain atomic)
