okay...  guess what?  I had mgetty/vgetty compiled with the wrong locks
setting (should be set to zero).  Thanks for all the hints and help.  I
guess that erroneous setting in the makefile can lead to lots of time
wasted troubleshooting a problem.. 

But after fixing that it seems to work fine now.  The only other thing I 
have not figured out is how to get vgetty to answer first with voice, 
then fax, and finally data.  It does the first two without any problems, 
but just hangs up after the fax attempt fails.  Any hints for this one?
