How to run my application at system start
in a way that doesn’t block consoles start ?
(/dev/con2…4)
When I run my app at the end of rc.local
consoles (/dev/con2…4) don’t start.
/ ++<1…4> doesn’t work 
have you tried putting a & to make sure your command starts in the background?
Is it possible your application isn’t using 100% of the CPU?
I can’t start it with ‘&’ - I’m waiting for keyb input,
and my app takes about 1% of cpu time;
I’ve managed a bit:
- QNX automatically logon
and I start my app (with root suid) from /$HOME/.profile
