Has anybody conquered | this problem? I'm typing on a silly Wyse 50 terminal right now. I presume the 60 is similar. To get to columns greater than 95, you need to modify the termcap entry so it uses the alternate form of cursor addressing. (Sometimes, vi is out there by virtue of having printed characters, but whenever it needs to get out there *directly*, you lose... hence the intermittent nature of your problem.) Specifically, for the 50: :cm=\E=%+ %+ : is the way to get to cols 1-95 (since the column number is encoded ASCII, and wraps after 95), while :cm=\Ea%i%dR%dC: is the way to get to cols 1-132, since the column number is a decimal integer. Notice that this is longer, and will take more time a low baud rates. Too bad. I just noticed that the /etc/termcap on our system uses the first 'cm' for the wy50 entry, and the second for the wy60. I don't know if someone locally patched it... you might check. Of course, if you are already using the longer cm, good luck. -- Randal L.
