My problem turned out to be some bad default settings in the modem. It's a hand-me-down modem, and the power-on/reset defaults had been set to use 19200 as the max speed. I could have changed the defaults, but I opted to just add the correction in my init string. Now I'm getting 26400 out of this 28800 modem, much better than the 19200 I was getting.
