[CentOS] External Dial-up Modem

I am having an issue with Centos 6 and an external USRobotics modem. We use the modem as part of a last resort SMS paging system.

Across multiple Dell servers, different models, I can't not get the modem to respond to simple AT commands while using Minicom. At the same time if I connect the server to a console port on a switch I can successfully access the switches serial console. So I know the serial port itself is working. The modem still works fine if connected to a Centos 5 server.

Any thoughts?
