I have a problem with the hardware configuration and analysis program
for our SciTech Display Doctor product. In order to do color console
output we are currently using a version of our console library ported
to run on top of ncursese. However this is causing us some grief
because we need to be able to display messages while we have the
console in graphics mode (while we are analysing and testing the
graphics hardware and BIOS capabilities).
One easy way to solve this is to use our direct VGA console library
which talks directly to the screen. This works perfectly under Linux
right now, however the problem is that when we exit we need to be
able to tell the Linux console to move the cursor location to the new
location that our console library has changed it to, so that it does
not overwrite our messages on the screen. Hence I am wondering if
there is a kernel call that we can make to move the console cursor
location? Alternatively how can we simply always move the console
cursor location to the bottom of the screen (some kind of escape
code?).
Also is there a kernel call that we can use to disable the console
scrolling which is done with the hardware panning registers? I know
that switching virtual consoles does this, and we would like to be
able to clear this before displaying our messages...
