   I'm not sure exactly what you mean by the terminal "flashes," but I'll
guess that you mean what is usually called "snow." Snow is caused when
there is a conflict in accessing the video controller. It can be programmed
around, in that you can tell your program not to try to access the
video while it's busy. Evidently, the terminal program you used didn't do
this, and thus caused the snow.
