Errors occured while attempting to edit the terminal initialization
file /etc/ttys during this procedure. A temporary error file called
/usr/tmp/ed_errs  is created to trap  any  errors  that might occur
while attempting to add a  terminal device  using  this  procedure.
Check /usr/tmp/ed_errs to determine  the  nature of the error,  and
then check /etc/ttys to see if a valid entry was made for tty01.  
Refer to the Guide to System Environment Setup for more information
about  the terminal initialization file /etc/ttys, it's format, and
description of it's entries; or contact your system administrator."

SS_ERR="
The software needed to support printers is not loaded on this machine.
You can load the necessary subsets using the SCAMP Install/Remove
Subsets option if you have an ULTRIX Software kit and an installation
device, or see setld(8) for more information on how to load software
onto this machine."

FILE_ERR="
The '/usr/lib/lpdfilters' directory could not be found on this machine
by SCAMP, which uses files stored in the 'lpdfilters' directory to
properly setup a printing environment.  Check '/usr/lib/lpdfilters'
to verify whether it exists or not, and then refer to the setld(8)
manpage for instructions on how to delete and then install subsets
on your system.  The 'ldpfilters' directory and it's files are located
in the 'PRINT' subset that is shipped with ULTRIX software."
