Hiya I'm looking at using asyncio for creating an socket <-> serial protocol bridge, but looking at the current implementation of asyncio it looks to be quite socket specific. I can't see any way to get it to support a simple serial device. Any advice on where to proceed would be very much appreciated! Thanks! James

You might have more luck on the python-tulip list/group. Asyncio is still very new for most people :) Cheers, Phil > > Thanks! > > James > -- > https://mail.python.org/mailman/listinfo/python-list

Never tried it, but if you can open the serial device and get its file descriptor, you should be able to use http://docs.python.org/3.4/library/asyncio-eventloop.html#watch-file-descriptors BTW, the specification doesn't indicate if the reader/writer callbacks are level-triggered or edge-triggered. I'm afraid they are level-triggered. At any rate, asyncio looks like a real positive development in Pythonland. Marko
