anyio-serial 0.3.0

Quick and dirty serial bytestreams for anyio

A small Python wrapper that combines anyio and pySerial.

Implementation detail: This library is using too many short-lived threads. Yes this should be improved.

Quick start

A simple serial port reader

anyio_serial is a reasonably intuitive mash-up of pySerial and anyio’s Stream:

import anyio
from anyio_serial import Serial

async def main():
   async with Serial(port='COM1') as port:
      while True:
         print((await port.receive()).decode(errors='ignore'), end='', flush=True)

anyio.run(main)

API

anyio_serial’s interface is really simple:

from anyio_serial import Serial

async with Serial(...) as port:  # same options as serial.Serial
   ...
   # use "port" like any other anyio ByteStream

Attributes

The states of the serial status lines cd, cts, dsr and ri are supported.
