Ok guys, Time to put this to an end. 
First in reply to Mr Logie: May I suggest something really radical? 
Like asking Pyramid Support!. The phone No is 008-027962. So as well as
getting some answers, you don't even pay for the call ;-).

Now in responce to Mr Bestel. You have some quite novel Ideas!. 
Sysadm in OSx 5.1 !!!!!!!!!. Is this a secret port that only exists 
in the land of softway?? Please share it with the rest of us. I'm sure
we'd all be interested!. And I'm quite sure that an "ls -al /dev/ios0"
would show thus: crw-------  1 root      44,   0 Feb 11  1990 /dev/ios0
But what would this prove?. This is OSx remember Not SVr4.  

And finally a warning to all.. Regardless of what Mr Bestel implies, 
there is a big difference between Single ended and Differential. If you
get it wrong you CAN release some of the smoke that makes all the little
chips work!. And as we all know, once that smoke is released there is no
way of putting it back ;-).
