Very Computer

I hope that someone can help...
I am a fledgling SA that just happened into the position (I knew more
about computers than anyone else here).  Our system was upgraded from
Xenix to Openserver Host (5.0.0c) about six months ago.  Since then the
"support" we were receiving has been terminated.  However, my problem is
this...
  I am using SCO Host system ver 5.0.0c with the d-patch installed.  We
have a 32-port Digiboard installed as a serial device and Wyse terminals
connected via line drivers.  Whenever we attempt to print to a printer
other than the terminal we are at (say from ttya05 to ttya11) the
program we are using gives us an error saying that the port is
unavailable.  If we change the permissions for that device, we can print
to that port, but only once since for some reason the permissions get
changed back.  We have tried using umask, but it didn't work.  (This was
not a problem before the upgrade).

Anyone have any suggestions for other things to try?
Any help would be appreciated.

I am not quite sure how you are printing. Aparently directly to
/dev/tty????. If this is the case, try putting a mesg y in
/etc/profile.

I gather that the printers are attached to the terminals?  You are
printing to a pass-through port?  What is the error you are getting
(exactly)?  What is the application?  Can you print to the printer from a
UNIX prompt ($ or #)?  What is the device name and what are the
permissions you are changing and what are you changing them to?  Who owns
the port (both owner and group ownership)?  Are the printers defined in
the lp subsystem or are you cat'ing the info directly to them? Are you
using Digi's MPI facility to define these printers?

Umask will only affect the permissions on *newly* created files, not
existing ones .... what is the umask value you are applying?  What do you
mean this was not a problem before the upgrade?

This requires your application to provide its own device locking to
prevent multiple users from printing to the same printer at the
same time.
