Putty & teemtalk

We currently use teemtalk as our emulator. It works fine but it doesn't
support colour. I'm trying to use Putty emulator insetead of teemtalk
but I can't get it to display correctly. I can enter my login name &
password no problem but after that everything goes wrong. I tried
different settings but no success. I included my teemtalk settings and
I hope someone would help me to find which setting to use for putty?
I got terminal type as follows:
$ set | grep TERM
TERM=wy50
but when I longin Putty I get a message "unknow teminal type wy50"
Can anyone help?
Thanks.
