terminal setting problems

in my bootscript im running sh on /dev/ser2 using:
waitfor /dev/ser2
reopen /dev/ser2
[+session pri=10r] /bin/sh &

this seems to work fine to open up a terminal but i found that it was
displaying to my terminal (vt100) incorrectly, the formatting was all
screwed up. so i did a stty term=vt100 </dev/ser2

this seems to have no effect.
so how do i put this shell into vt100 mode?
