One of my branch offices has a 2821 router that I would like to connect a modem to for dial-in connectivity in case of an emergency. This branch office is about 2500 miles away from the office I work at, which is why I need this emergency access. Once I connect the modem to the AUX port on the router, is there any configuration I need on the router? If not, should I just use HyperTerminal or TeraTerm to dial into it? Thanks.
