The VMS terminal >driver for the DMF-32 did not use the feature until VMS V4 came out. >At that point, it became evident that many DMF emulators weren't. So *that* explains it! Except for one small point: when I put this into my Unix kernel, I got this very same behaviour, but we have a *DEC* DMF32. . . . Perhaps some DMFs aren't, also. Chris
