The script for 7.0 sam (/usr/sam/bin/mkterm.sh) that creates the device files
and puts the appropriate entry into /etc/inittab was not written by an S.E.
This script was derived from a previous one (perhaps the one the SE was
referring to), but the bug was introduced in support of modems on series 300
machines in 7.0.  It ONLY creates the wrong device file if you are adding a
modem (terminals are not affected) on a series 300 machine with a select code
greater than 9.  All other configurations create the correct device file.
I am not aware of any problems with the entry in /etc/inittab, if you are,
I would very much appreciate any details that you can offer.  We are always
concerned about any bugs that have made it out the door and want very much
to identify them as quickly as possible to get them corrected as soon as
possible.  The defect in the shell script has been corrected for 8.0 and
there is a very simple workaround/patch available to you.

If you want to do it yourself, just edit the script above and move line #335
which looks like:
	lu=`echo $lu |awk '{printf("%x",$1)}'`
to line #295 immediately after the comment:
	# remove old device and recreate

That will fix it.  Again, I'm not aware of any problems with the entry
created in /etc/inittab (except that if you add a modem in the manner
described above, the entry obviously won't function as intended).  Any more
details that can be offered for any bugs you've seen here will be greatly
appreciated.

Thank you,
