pySerial-asyncio

pySerial-asyncio is an asynchronous I/O extension for the Python Serial Port package (pySerial). It provides support for working with serial ports through asyncio Transports, Protocols, and Streams. Compatible with Python 3.5 and later, it depends on pySerial. The current version is 0.6. The project appears to be in maintenance mode, with no new releases since 2021, and a fork `pyserial-asyncio-fast` addressing some critical issues.
