Rok,

I don't know if this applies to your hardware setup, but I set our IOC
to run on one of the virtual terminals on our Linux box. I did this by
modifying /etc/inittab by first commenting out the old entry for tty6
and then adding:
ioc:345:respawn:/bin/su -l bl72 </dev/tty6 >/dev/tty6
bl72 is the account for the IOC, and has a .cshrc file set up in its
home directory to start the st.cmd file.
If you don't have virtual terminals, you should be able to redirect I/O
to some other device, a file, or /dev/null.

Hi all!
I have an interesting question. How to run EPICS application on a
linux box in a background. The box is actually contains a strong-arm
processor with all the data (+EPICS) stored in the flash. I would like
to get EPICS started as soon as I turn on the machine. But if I write
a script and put it into /etc/init.d/S99epics, the application starts
and then immediately ends.
I cannot use Dirk Zimoch's shellbox.tcl, as I have no tcl. I have also
no screen program now. Everything else works very well on this
platform, including serial device control with (for now) gpibCore.
Can anyone give me a clue about this, please. Should we patch EPICS a
bit or is this solveable with linux tricks?
Cheers,
Rok
