Using asyncio for serial port

[james.time4tea]

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!

You might have more luck on the python-tulip list/group.

Asyncio is still very new for most people

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.
