What exactly do you mean by "serial line monitors"? You've
got them tapped into a line that's carrying traffic between
two other devices? If so, you need additional hardware to make
the electrical properties of the cables be correct at all the
ports involved; failure to do this can have all kinds of
strange effects. I'm not sure exactly how to do it (other
people build the proper cables for me), but that might be
a factor.
