Quickstart

Install serialx:

pip install serialx

Open a serial port synchronously:

import serialx

with serialx.serial_for_url("/dev/serial/by-id/port", baudrate=115200) as serial:
    serial.write(b"ping")
    data = serial.readexactly(4)

Open a serial connection asynchronously:

import serialx

reader, writer = await serialx.open_serial_connection(
    "/dev/serial/by-id/port",
    baudrate=115200,
)

For optional transports (ESPHome, RFC2217, socket) and compatibility notes, see Installation. For more patterns, see Usage.
