tcdrain or tcflush for flushing #99

In this https://github.com/dotnet/corefx/commit/45dba6ea7a49a9945a5ad497cfc3de2ec1246683#diff-221055955142c33d285c9271ba435005 .NET Core team replaced tcflush with tcdrain. Maybe SerialPortStream should use tcdrain too, because tcflush discards bytes, but Flush() API should send them.

https://linux.die.net/man/3/tcdrain:

tcdrain() waits until all output written to the object referred to by fd has been transmitted.
tcflush() discards data written to the object referred to by fd but not transmitted, or data received but not read
