umoria on the 3b1:problem

[Arthur Wouk]

i have brought the source of umoria, the unix port of moria4.5 to
my ATT UnixPC, also known as a 3b1. it now plays properly with one
hitch. after i save a game with ^X or else quit with Q, the screen
echo is gone from the shell from which the game was called, although
not from other shells. is this a known bug, or have i done something
wrong in my compilation? is there a simple way to restore the screen
echo without kill -9 'ing the shell?
