A pts device is also a tty. I have troubles understanding what you want to 
achieve (and to be frank, none of your mails are explaining), but if the 
problem is that your application is SCO-centric and cannot work with pts 
devices, then you'll have to find the source code or ask your vendor.

(Or simply log on to the console instead of using SSH ?)

The way the tty command finds its tty is by following the 
/proc/self/fd/0 symlink.

[root at moria root]# ls -l /proc/self/fd/0
lrwx------ 1 root root 64 Dec 30 03:40 /proc/self/fd/0 -> /dev/pts/3

Not sure what your application is doing to, try stracing it to find out.
