I should know the answer to this problem; but I never wrote it down and now
I forgot :(    At one time, I thought it was a problem with scologin, and
recommended to those affected to try stock MIT xdm (which we use here anyway,
ripped from a previous version of ODT).

For now, check to make sure that you are NOT listing the Xterminals in
some kind of Xservers file on the host (typically /usr/lib/X11/xdm/Xservers,
but is something else in sco using scologin).  XDMCP replaces the Xservers
file, which is long obsolete (for everything except starting XDM on
the console Xserver).

We have been running several Xterminals on our network for quite some time
now, and have never had XDM hang or otherwise cause any problems.  (ODT2.0)
