Wyse terminal modes

This is probably not a 10yr thing, but I don't know any other list that's got this many people that know what they're talking about... I've got a Wyse WY-50 terminal. From the menus, it's got four modes: FDX, BLOCK, HDX, H-BLK After reading (on this list) that the old HP terminals had something called "block mode", I was wondering what it meant here. Also, what's FDX and HDX? The first thing that came to my mind was Full Duplex and Half Duplex, but I don't know how those would apply. Also, are these terminals just really lacking features or are Linux and *BSD just not running it right? It seems that tabs get ignored, for one. And it is just generally awkward looking. (And the arrow keys don't work in pine, but that's not terribly critical.) It doesn't act in a logical way at times. What were these terminals meant to be used with? I got this one from a AS/400 installation, though I don't know if it was ever actually used for the AS/400 (they had a whole mess of IBM twin-ax terminals for that). af ------------------------------------------------------------------------------- Adam Fritzler | afritz(a)delphid.ml.org | Animals who are not penguins can afritz(a)iname.com | can only wish they were. http://delphid.ml.org/~afritz/ | -- Chicago Reader http://www.pst.com/ | 15 Oct 1982 -------------------------------------------------------------------------------
