Follow this link and click on the section "Installing the Router Software Using the Console or Auxiliary Port"

Scroll down a fraction and take a look at the xmodem description:

The following example shows how to use the xmodem [-cyrx] [filename] command on a Cisco 3600 series router:

rommon 1 > xmodem -c c3620-i-mz.0918..............

thanks guys, but i have already tried using xmodem. it appeared to have worked. but the next day after the router had been put off. it returned back to its former status with the image of the 3640 still there. the problem i have is that the xmodem down load does not appear to erase the current image. any idea's?

Didn't you first erase the existing image ?

First boot it and delete the existing image and then download the new one.
