Electronic charting without a serial port...
The Dell inspiron line has 9 pin serial port. I have been using it with my maptech offshore navigator software for 2 years connected to either my Garmin 3 or 48 without any problems. It works great. Garmin provides the wiring diagram for the connection to the 9 pin connector. The wiring takes about 10 minutes of soldering.
Hope this helps. I also have limited tech, knowledge, fortunately all of the wiring was color coded.
