This patch solves the problem of receiving "error" responses when
initially calling gcom. This avoids unnecessary NO_DEVICE failures.
A retry loop retries the call after an "error" response within the
specified delay. A successful response will continue with the connection
immediately without waiting for max specified delay, bringing the
interface up sooner.
