Perhaps one of you guys can help me.

I have an Amada Ariess 222 with Amadan 03P control, which I gather is actually a Fanuc in disguise.

Its been in storage for a couple of years, and now refuses to accept any attempts at serial IO. The actual message that pops up when I try it is "Operation Error", which from the manual, is what you get when you try serial IO operations on a machine that is not fitted with the optional SIO ... except ours is fitted, and used to work, so I figure the machine has just suffered a bit of memory loss in storage ... everything else functions just fine though.

So, any clues on how to get to the parameter page etc, I'm sure there will be a self explatory "SIO" or something parameter that just needs flicking from 0 to 1 ...
