Re: No Parallel Port

Aha !

the problem appears to be that I've been editing the EMC.INI file whilst the
EMC application is actually looking at GENERIC.INI.

Not sure if this has changed or I've done something recently to modify this.

I'm really sorry for clogging the message list with this novice stuff !

What controls which INI file is looked at on startup ?

thanks!

Phil
