I would like to find a way to have more than one set of init strings for one modem. Specifically, I use a Motorola BitSurfr Pro (external) for internet access. As it costs me more for bonded access than for single channel, I only use bonded when the extra bandwidth is necessary. Bonded v. single channel is controlled via some init strings entered into the "Advanced" config menu for the modem. Unfortunately, when init strings are entered here for one DUN connection, they appear on all the DUN connections using that modem. Any suggestions?
