Cannot write on port #17

Closed AhmedMannai10 closed 2 years ago

I can get the ports, connect to them and read data. but I cannot write writeBytesFromString and writeBytesFromUint8List always returns false

dart .

Actually, write successed. It's due to overlapped mode. Write Operation will always return 0 and GetLastError will retrun 997 error code which means ERROR_IO_PENDING.

Fixed it.
