I am having problems with my 1760 router which got a rommon prompt upon rebooted. And I tried to upload a backup image using xmodem from a PC. And it was accidentally disconnected during the transfer progress. And since after than I cannot type anything at the rommon prompt to download the image again. I can still see the rommon prompt now but I cannot type anything there. Ctrl+Break works but cannot type anything. Would be very much appreciated for any helps.
