As Dave Gunn ( says :

The problem breaks down into 2, eeprom and tty.

Here's Dave Haut ( answer to the eeprom problem :

> Don't worry. Power off your SS20. Hold down the stop and n keys and power

> This should reset your eeprom to its default values and you should be

and Fred <> answer to the tty problem :

> Remember that you need a null modem cable, or a null modem adaptor,

Checking the cable I had I discovered it was crossed, so changing it to
straight through meant I could log in and change the fs prob.
