Dealing with dial-up lines

[Xev Gittler]

When a person dials in over a modem line, and then hangs up without
logging off, the computer should know enough to kill those processes,
right? (It should get a hangup signal?). Could someone suggest why on
my 4.3 system, peoples jobs would be just staying around, and the next
person that dials in to the same modem will come in in the middle of a
session?
