using serial port in python3 asyncio

Question

i\'m trying and, so far, failing to use python asyncio to access a serial port.

i\'d really appreciate any tips on using the new python async framework on a simple fd.

Answer 1

Consider using aioserial.

Here's an example:

import aioserial
import asyncio


async def read_and_print(aioserial_instance: aioserial.AioSerial):
    while True:
        print((await aioserial_instance.read_async()).decode(errors='ignore'), end='', flush=True)


aioserial_com1: aioserial.AioSerial = aioserial.AioSerial(port='COM1')

asyncio.run(read_and_print(aioserial_com1))

To the moderator,

The answer is just similar to this one but not duplicated.
