Hello,

I am trying to write asynchronous serial port.
meaning, read and write operations are made via async cllbacks.
so far so good.
I open my port in continues state:
1)Set the BytesToRead property of the serial port.
2)open the port
3)generate read request
4)meanwhile generate write request.
5)in result, the read operation is executed(provided that the BytesToRead are
present n the stream)
i encountered a problem that despite of Setting the BytesToRead property,the
read operation is executed and reads 1 byte from the stream.
after the read operation is completed i generate another async read request
so the port is always in "Listening" mode.

am i doing something wrong?
can't i work asynchronically?
do i have to lock the stream or the port or the buffer itself?

Thanks
