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. Signed-off-by: Mike Wilson <mikewse@hotmail.com>
