Watch ‘Downton Abbey’ special

There will not be a new episode of Downton Abbey on Sunday, most likely to avoid competition with the Oscars. But that’s not to say there are no Downton doings. PBS’s Masterpiece will present a More Manners of Downton Abbey special at 9 p.m. Sunday, the usual Downton spot. According to PBS, it “explores the social protocol of aristocrats and servants in the 1920s,” and features interviews with some cast members.In addition, WNEO/WEAO (Channels 45/49) will have a marathon of Downton episodes from the current season beginning at noon and continuing until the Manners special. The series finale of Downton airs on March 6.
