264 Packet format for an RR channel request:
266 4 bytes = channel ID = 1 (request/response channel)
267 4 bytes = request ID (from serialNumber)
269 4 bytes = length of the rest of the packet
270 ? bytes = rest of packet. depends on packet
273 Packet format for an RR channel response:
275 4 bytes = channel ID = 1 (request/response channel)
276 4 bytes = request ID (from serialNumber)
277 4 bytes = length of the rest of the packet
278 ? bytes = rest of packet. depends on packet
281 Packet format for a stream packet:
283 4 bytes = channel ID = 2 (stream channel)
284 4 bytes = stream ID (from requestID)
285 4 bytes = length of the stream data (rest of packet)
286 ? bytes = stream data
