iDirect 3000 modem rebooting

Hi,

All was fine until i loaded what is seemingly a bad option file and the modem now keeps rebooting.
I am able to ping it but i cannot telnet into it using a cross cable back to back. So, i have used a console cable and am able to login as root. I can no longer login as admin.
How do i then reload the old option file using hyper terminal? I recall someone advised to cut and paste. How do i go about that? In which directory does the option file reside on the modem?
