Do you think it is DOS 3.1? I really liked that.
back when I was doing testing of UAV-SRs for the U.S. Navy in 1990 and 1991, they were running UNIX. I still intercepted and recorded their entire comms links, video downlink (seeing what they were seeing), and the C&C.
my very first comment to my chief with me was why the fuck is this not encrypted chief?
