From the FAQ: The emulation level for xterm is set via the resource decTerminalID, *e.g.*, to 220 for a VT220. Once set, applications can set the emulation level up or down within that limit. DEC's terminals are configured in much the same way by a setup option. Yup... .Xresources has "decTerminalID: vt200" but that still doesn't excuse it for misbehaving as one. ;) It also doesn't do DECDWL or DECDHL when it's set for vt200. Note that the value should be set to "220", not "vt220", nor "vt200". Actually, for me: xrdb -query | grep decTerminalID gives *.vt100.decTerminalID: 220 Check that you have things actually set correctly... If you just have decTerminalID, it will not even be associated with xterm. (Xresources are often a somewhat obscure thing.) DECDWL and DECDHL works just fine for me. That could be a font issue in your environment. Johnny
