     A big thanks to Bob and all the others who took time to respond!

      It turned out that this *WAS* a DNS issue.  Their networking guy moved
their  DNS from 172.16.1.254 and didn't tell the rest of us systems guys.
Commenting out their old nameserver line and adding  their 2 new nameserver
lines to  their /etc/resolv.conf  file  fixed FTP:

#    nameserver 172.16.1.254
nameserver 172.16.1.12
nameserver 172.16.1.10

     Apparently, at least on SCO Openserver 6, FTP is dependent on DNS
working correctly, whereas telnet, ssh, ping, http and  FacetWin do not need
the correct nameserver.

     Since all their Windows machines still show a gateway of 172.16.1.254,
I'm not sure why all the services seem to be working on those boxes.
However, I will let their networking guys and their Windows and Netware guys
take care of those issues.

Thanks!
