 The Digi's use _10_ pin RJ connectors, and one of the important
 signals, DTR I think, is on one of the pins you usually can't reach.
 ditty has a switch called altpin that swaps the one you need for one
 you probably don't.
 
 Hope this is enough hint.
 
 And I hope they're running HylaFAX on it.  :-)

It sounds like IBM used the same Digi Concentrators with their RS6000 RJ45 
128 Port RAN Concentrators. If so, the pinouts are probably the same as it 
too uses 'alternate pinouts' for only 8 leads or normal for all 10 leads. IBM 
has all the cabling options and pinouts documented, so if these are the same 
boxes, you could get what you need from the IBM docs. We have 4 of these RANS 
(each 16 ports) for 64 ports (of the max of 128) and use the both for modems 
and dumb terminals. Drop me an email at kabrahamsen@wrightgroup.com as all my 
reference material is at work if you're interested.
