I'm looking at it right now and I'll try to force this
hanging device scenario on our test box, of course. But
When it is really needed, is when work places in the
factory stands still and really need to get going.

And it must be possible to use it in the COM files that
the users can submit from there menu system.

Today, I simply change the appliation startup COM file
and assignes another unused TNA device number and let the
hanging one die by its onw. Actually, the device in my first
post above (TNA8883:) is gone now, a couple of hours later.
I changed the COM file to use TNA8884: instead so that they
get the printer online again and then left it like that.
And now TNA8883: is simply gone...

The TNA device points to an IP and port number of a label
pinter (Zebra). Sometimes when the printouts hangs, the users
simply close their session and that is where the user process
goes away and the TNA device gets hang, I guess.

I also have another idea where a pool of TNA numbers are used
in a round-robbin fashion. Then we can let any hanging devices
just go away by their own.

But I'll look at this first and we'll see...
