Error/Problem with Vtclock.c

[Joseph P. Thomas]

I installed vtclock.c, replacing SIGUSR1 (which our site doesn't support),
with SIGURG (defined as signal 16). The windowing and display works okay
but I run into a problem when it comes time to restore the cursor. Instead
of returning to the old location, the cursors homes, but does not clear
the screen. All the escape codes match the manual, so I imagine that the
problem is in the save/restore, or in my changing the signal. Anone else
run into similar problem or know a fix ?? Thanks.
