Since this question seems to come up a lot on the net, as my parting 
shot from Hayes I'll attach below the DIPSWITC.TXT file that Hayes 
uses to answer this question.  It describes the switch settings for 
all of the early products.  If someone ever gets around to doing a 
FAQ for this group, this would probably be a good thing to put in 
it.

The next message you see from me is likely to be from Microsoft!
