By "the quad version" I assume you mean the M8043 (DLV11-J) or 3rd-party equivalent. Since I didn't have one of those when this video was made and this video was about making use of available resources, that is not really a practical suggestion. Also, had I needed current loop or modem control, the M8043 would not work - the M8028 (used in the video) and M8017, respectively, support those capabilities.
use the quad version
