Does anyone know how to stop the cursor from blinking in DOS? It doesn't annoy me enough to load a TSR program, but if there someone can provide me with locations I can patch using DEBUG, I would appreciate it. I'm using DOS versions 3.1 and 3.3. While I'm at it, how about a way to assign new functions to some of the function keys when at the DOS command level? I'm happy with F1, F3, and F6, but how about the others? Also, I have been using the "C" shell (/bin/csh) under UNIX, and have quickly grown used to the file completion (set filec) feature. Anyone know of something similar for DOS? If not, I may attempt to write my own... Thanks Doug

As far as I can tell it's a hardware feature. There are programs which give a non-blinking cursor by turning off the hardware cursor (set start and stop lines to 15 as I recall) and doing it in software. If you really want to stop it I think you can cut a trace, at least on the mono and CGA boards. -- bill davidsen (wedu@ge-crd.arpa) {uunet | philabs | seismo}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me

This is for colour systems. I am not sure what the scoop is for mono. Hope this helps. pavneet parora@utgpu

This is for colour systems. I am not sure what the scoop is for mono. This is not true; the blinking of the cursor does not come from the background color or blinking attributes. It is true that the cursor takes its color from the background, but as to the blinking, no. As far as _I_ know, there's no way other than turning it off and writing software to do your own cursor. >pavneet >parora@utgpu Harlan hwfe@tut.cc.rochester.edu

Here is a program that will turn the cursor on or off. It uses
the BIOS Video call (INT 10H). This program is actually a modified
version of an example program in the MSC 5.1 Reference Manual for the
"int86" library routine (on page 366). The actual code to alter
the cursor is only 4 lines.
Hope this helps...
