267 Packet format for an RR channel request:
269 4 bytes = channel ID = 1 (request/response channel)
270 4 bytes = request ID (from serialNumber)
272 4 bytes = length of the rest of the packet
273 ? bytes = rest of packet. depends on packet
276 Packet format for an RR channel response:
278 4 bytes = channel ID = 1 (request/response channel)
279 4 bytes = request ID (from serialNumber)
280 4 bytes = length of the rest of the packet
281 ? bytes = rest of packet. depends on packet
284 Packet format for a stream packet:
286 4 bytes = channel ID = 2 (stream channel)
287 4 bytes = stream ID (from requestID)
288 4 bytes = length of the stream data (rest of packet)
289 ? bytes = stream data
