Pretty hard to do without including setterm in PROM on an embedded
system. `strace` shows that setterm just sends an escape-sequence. It
does not use an ioctl for this function.
This does it:
const char blk[]={27, '[', '9', ';', '0', ']', 0};
main()
{
printf(blk);
}
However, including this in the code to keep the console on is, err...
somewhat hokey.
Looking through the console code, I see how to keep the screen from
timing out. However, I can't seem to locate an external entry point.
Basically, I was looking for the functional equivalent of:
ioctl(1, DO_NOT_BLANK_THIS_EVER);
