[New-bugs-announce] [issue32396] Implement method to write/read to serials without blocking on windows with asyncio

[jabdoa]

New submission from jabdoa <jan-python at kantert.net>:

This is a follow up to Issue30539. The main issue is that serial ports on windows do not behave like socket on unix. Therefore, pyserial-asyncio cannot use the asyncio socket api.

Can we implement serial_recv and serial_send in asyncio? This would help to create a true platform independent implementation. On Linux and Mac serial_send/recv could probably just call to socket_sendall/recv. On Windows this would map to ProactorEventLoop.send/recv.
