tcflush on open may cause data loss about serialport-rs

[jannic]

Another observation: At its current place, that TCIOFLUSH seems to be completely useless, as it happens before the port is configured to its final baud rate (and other settings).
Therefore, there is still a window where garbled data could be received and placed in the input buffer.
My suggestion still is: Just remove that line.

Damn i was just going to ask a question about how to clear the buffer properly since i was still receiving garbage invoking port.clear(ClearBuffer::All) just after opening the port. Is this also useless? Is there a viable way to properly clear the buffer in this version?

@kaluk1321, that sounds like a different issue. If you call port.clear(ClearBuffer::All) manually, that's obviously after open() has been executed successfully. So your call should remove garbled bytes received before the settings were applied.
