pyscript equivalent to HA yaml "mode: queued"

[dy-nz]

I'm new to HA, and even newer to pyscript.
After fighting with automations, bash scripts and nc/netcat so that HA can talk to my devices (two of which are multizone amplifiers, one a receiver), I've just discovered pyscript and import telnet. Relief :-)

I have one significant thing I can't find a pyscript solution for. I use the HA yaml "mode: queued" to ensure that only one HA action is telneting with one of my devices at any one time. It is simple to use. Is there a pyscript equivalent please ?

Thanks.

First, you should be using asynctelnet instead of the vanilla telnet module to avoid blocking.

To ensure your telnet I/O is serialized among multiple callers, you should use asyncio.Lock(), or one of the other async synchronization primitives. See #340 for an example.
