[Lazarus] Using SdpoSerial, how to clear buffers?

[Bo Berglund]

I have started to code using the SdpoSerial component and now I am in
need of a way to clear the receive and transmit buffers.

I have not found any useful method in the TSdpoSerial object but it
exposes the underlying SynSer component so by testing this I found two
candidates:
var
  FComm: TSdpoSerial;
begin
  ...
  FComm.SynSer.Flush
  FComm.SynSer.Purge

What does these methods do? Are they useful to get rid of stuff in the
comm buffers when starting over with the communication protocol?
