These number actually sound reasonable to me.  MS Word is a pretty power
hungry application.  It's CPU usage might drop in 386 enhance mode, but I
am not sure about that.  As far a ProComm goes, running a DOS application in
a window takes a lot of CPU time because Windows has to virtualize the
text screen (where procomm normally write), convert that screen to a
graphic bitmap and dump that bitmap to the screen at regular intervals.
Running DOS applications full screen takes considerably less CPU time.
