Remove the script and make it an alias or a function or something
like that. This will get rid of the unnecessary parent shell:
$ cat >>.profile <<eof
pppmode(){
tt=$(tty)
exec /usr/sbin/ppp -direct ${tt##*/}
}
eof

$ cat >.profile <<eof
. /home/service
eof
$ cat >/home/service <<eof
tt=$(tty)
echo -n "Service: "
read svc
test "$svc" = ppp && exec /usr/sbin/ppp -direct ${tt##*/}
...
eof
