I have configured it to output GGK or GGA to a windows computer. My experience is that it is not very stable however it does work. Yes you will need to connect to the receiver though the web login and configure it that way. I have had the best results by first connecting to the 442 with a null modem cable then changing the IP to Static and giving it a static IP of somthing like 205.210.10.1 then connecting to it with a crossover cat5 ethernet cable and typing in that address into my web browser. The default username is "admin" and  the password is "password". Someone correct me if I am wrong. this will give you an entirely new prospective of the 442 if you have never seen this web browser interface......it is very well done.
