I have a new system which I am evaluating, as a full-time RV'er. It is a Nokia 6120 phone with modem cable, and 3COM cellular/fax modem card, in a Gateway Solo notebook. So far, I have had no problems connecting, however the speed is limited to 9600 bps, which is slow. I am finding, however, that the phone is very easy to use for data transfer, as it self-configures for data use, (i.e. changes to analog mode, etc.) This system still can't tx/rx digitally.
