IOS Upgrade through Modem

I have an IOS upgrade scheduled on a 2800 router and I have to erase the present IOS.  This is a remote location.

I am worried that if the new IOS does not work properly that the router will boot in rommon mode.

I would still have access to the router via a modem connected through the cosole of the router.

How would I upgrade a router IOS in rommon through a US Robotics Modem connection on the console the router and using a US robotics on my desktop computer to dial into the router?  I cannot locate any documents on the Internet about this.

Has anyone done this before?

All responses are greatly appreciated.

You have nothing to worry. After copying, use the verify command for the new image.

Just do not delete the old image for a while in case the new one is buggy.
