Does SdpoSerial use buffers at all ? With AsyncPro, Buffers necessary to 
convert the blocking System interface into the event driven AsyncPro 
user API by doing the blocking system calls in threads. With the 
receiver, the collected data needs to be buffered until the main thread 
is available to handle it, With the sender, the data generated by the 
main thread needs to be buffered until the system API unblocks the 
interface it blocked to prevent overrun of the system buffers.

Without using threads the user just sees a blocking interface and no 
buffers are necessary.
