Just wrap data with a header and a trailer - ie
Psuedo-code:
|<----header------->| |<--trailer->|
send_data_buffer := 'H' + SizeOf(MyData) + MyData + CRC(MyData)
You can then process the first packet & know the length of the data &
thus when you have recieved the full amount of data. Pretty similar to
implementing X-modem really..
