Timeout?

[KammutierSpule]

Does it make sense to add a timeout capabilities ?

Or is possible to implement some flush/reset of the internal state?

Hi. Tnx for the question. What is the real use case of such feature? What would You like to achieve?

I'm wondering on cases with disruption in the lines. Are there mechanisms to recover?
Other cases: the other side hang or crashed.

Which side of the communication channel should retry after timeout? Master/Host/Server (cAT - which basically send responses only) or slave/client (external device with app which send requests and WAIT for responses)?

Slave/Client side is responsible for ensuring that the cAT is in the "ready" state. Its very easy to achieve just by sending "\n" or "AT\n" and waiting for response. In both cases its job for Slave/Client app, not for cAT library.
