UN*X license for BSD sources ???

[Narayan Mohanram]

I am considering including a part of the tty driver from BSD in
a product for non-un*x machines. It is the NTTYDISC part of the
tty driver. Will it require an UN*X license to distribute it. I
know that this code was developed in Austria somewhere, and did
not originate in AT&T.

Thanks for any advice in advance
