/**
 * A connection interface with a MAVLink device.
 *
 * All the methods are blocking and can throw [IOException]. This is a design decision to keep the interface simple and
 * to allow the user to decide how to handle the blocking calls and the IO errors.
 *
 * Normally, the users will use wrappers/adapters like the
 * [CoroutinesMavConnection][com.divpundir.mavlink.adapters.coroutines] which provides a coroutine based api to the
 * underlying connection.
