Hello. I understand that progress does not stand still , and I would like in the next update to return data transmission over the serial port as in GARMIN DNR . A lot of devices still use the RS232 interface . For example, the GARMIN strike 4 (plus) line of echo sounders. I would like to be able to unload QDC (QuickDraw Contours) files. This will help many people who are fond of active recreation . With respect to the developers .
