Async modem dial-in

I have a 1603R with an async serial card connected via a RS232 cable to a standard Hayes modem.

My question is the router seems to be configured OK but the Carrier Detect is not lit so the interface is always down. I have manualy set the modem to always enable CD AT&C0 and saved it to the stored config. This brings up the serial interface but the router then resets the modem and turnes off CD and so the interface goes down again.

Can anyone help?

Many Thanks

Please see if the document 'Sync-Async Ports for Async Modem Dial-in On Cisco 1600, 1700, 2600, and 3600 Platforms' helps. http://www.cisco.com/en/US/tech/tk801/tk36/technologies_configuration_example09186a00801d2576.shtml
