Yeah, it's MNP level 3, according to the manual. >UNFORTUNATELY, because of the different circuitry, a 2400 CANNOT be upgraded >to a 2400E . . . pity. Also unfortunately, the 2400E is a lot less reliable than a 2400. We ordered ten Courier 2400 units about two years ago, and have had only one flakey one in the whole lot. (For a $300 modem, I call that excellent. Granted they all were temperature sensitive, but that was easy to deal with.) We recently bought ten 2400E units, based on rave reviews from customers and friends. At least half are having problems, and they are of the flakey inter- mittent variety: random hangups, random crashes, random modem confusion. Problems are much more frequent when using MNP, and the MNP implementation itself seems marginal. We have a number of local MNP sites that Racal-Vadic and Telebit modems talk to just fine, but the Couriers never sync up, or will complete one MNP call and then need a power-cycle before making new MNP calls.
