One of the most frequently asked questions; it IS possible, but there is a
price you have to pay.

Solution I.
------------------------------cut here------------------------------
#! /bin/sh
#
# c: a script to change the prompt of the parent to the new working
# directory
# to put in $HOME/.profile:
#
#	PARENT=$$
#	export PARENT
#	trap 'DIR=`cat $HOME/.dir`; cd $DIR; PS1="$DIR> "' 5

cd $1
pwd > $HOME/.dir
exec kill -5 $PARENT
------------------------------cut here------------------------------

Solution II.
If your sh knows shell functions:
------------------------------cut here------------------------------
c()		# you cannot name this function `cd'
{
	cd $1
	PS1="`pwd`> "
}
