A pts device is also a tty. I have troubles understanding what you want to

You've got it; the application is SCO-centric
The application need to find a /dev/tty01 or more but can't work with
If you run the application as root, you could create a device node that is
identical to the real device as /dev/tty01 (since Linux uses /dev/tty1
they will not clash).
This can only work if you understand how the application is constructing
/dev/tty01 (I am sure this is not hardcoded, because that would not even
work on SCO).
The developper is no more active and I don't have the sources.
One of my last resource is to find a way to start a terminal and have Centos
allowing me to start the application on a terminal as tty instead of a
Even on SCO the application needs to figure out its own tty. So there
should be a way to influence its decision. I don't even understand why it
would go with /dev/tty01 over an SSH connection, unless it is hardcoded as
a silly fallback default if all other measures have failed.
Finding what these other measures are, may be the source of a solution ?
(Or simply log on to the console instead of using SSH ?)
This haven't been tried, and I will to morrow; but our best will be to use
it a text terminal.
You can also tru using 'conspy' to take over the real /dev/tty1 from an
SSH or screen session and then start the SCO application. However if the
SCO application expects /dev/tty01 then that would fail similarly.
Creating a device node identical to the current tty is probably the best
way forward if it really is /dev/tty01. You can do this simply by doing:
cp -aLv /proc/self/fd/0 /dev/tty01
or maybe a symlink would work as well:
cp -av /proc/self/fd/0 /dev/tty01
The advantage if a symlink is simply that you have a visual confirmation
to what tty it is linking without having to decipher the major and minor
Not sure what your application is doing to, try stracing it to find out.
There is no possibility to trace at start-up.
Man, aren't you glad that your SCO days are (almost?) (finally?) over ? ;-)
