I loaded the incorrect IOS image via tftp and in the process erased the flash. Now when i start up I get wrong system software for this hardware and get dropped into rommon> mode.
I read an article on experts in regards to using TFTP commands to re-download the image but the hardware im on (3640 router) doesn't seem to support tftp in rommon mode. See rommon options below.

rommon 2 >
There is also some documentation to use the boot option to load via tftp but no go.
The dnld option looks like it might be my way out but how does that work? i need to download an image via serial? do i make a serial connection with my pc? is it the 15 pin connector on the back of the hardware they are talking about or my wan serial connections?
