UP-3GHAT01: use com1

Hi,
I recently install UP-3GHAT01 and i wanted to use com1 to connect to a remote terminal, but i don't see the device after i plug the hat.

My up is the UP 2 and i installed ubilinux 4:
Linux ubilinux4 4.9.45-ubilinux+ #2 SMP Fri Sep 8 10:51:36 IST 2017 x86_64 GNU/Linux

I search in the quick install guide but there is nothing related or explain what module should i load.

is it possible to do what i want? can you help me?

Thanks.
