274 4 bytes = request ID (from serialNumber)
276 4 bytes = length of the rest of the packet
277 ? bytes = rest of packet. depends on packet
280 Packet format for an RR channel response:
282 4 bytes = channel ID = 1 (request/response channel)

284 4 bytes = length of the rest of the packet

288 Packet format for a stream packet:
290 4 bytes = channel ID = 2 (stream channel)
291 4 bytes = stream ID (from requestID)
292 4 bytes = length of the stream data (rest of packet)
293 ? bytes = stream data
