Situation resolved.

When upgrading from SCO OSR 5.0.6 to OSR 6, one of my
startup scripts (/etc/rc2.d/S99remprt) was no longer
useful, so it was deactivated by making these two lines
the first lines in that file:

  #!/bin/sh
  exit 0

Recently, when I was planning to change root's login
shell to be /bin/ksh I was advised that it might be wise
to see that all startup scripts had #!/bin/sh as their
first line.  It must have been at that time when I edited
/etc/rc2.d/S99remprt I accidently changed its 1st line to
be: $!/bin/sh (changing the # to be $).

So, when starting up, this caused a shell to run on tty01,
because (I'm told) the /bin/sh executing the scripts saw
the $! as an argument where $! was the PID of the last
process ran in the background and therefore NUL, so the
shell just ran, attached to tty01.

The file that contained all of the info about my attempted
logins on tty01 was /etc/rc2.d/messages/S99remprt.log - an
unintentional logging (phishing) by me of mine.

Sherlock Holmes (aka Jean-Pierre Radley) got on my system
and did an 'lsof' and 'ps' and a little other investigating
disclosing the root of the problem (user error - I'll never
know how I accidently changed that # to a $).

|  System:  SCO OSR6 (MP1, OSS702a, OSS702b and MP2)
| 
| Problem:  No user can log in on the console (tty01).
| 
| This just started recently, after a reboot following a kernel
| panic.  The Software Manager (custom) has no complaints after
| verifying all software installed on the system.
| 
| All users can log in on tty02-tty12 and, root has no problem
| logging into single user mode, but in multiuser mode . . .
| 
| At the initial "login:" prompt I must type each character of
| the user name and the [Enter] key twice before the "Password:"
| prompt appears.
| 
| After typing in the password I must press the [Enter] key two
| times.  I doesn't matter if I single or double strike the  
| characters in the password, I always get:
| 
|   Login incorrect
| 
|   Wait for login retry .
|   login: _
| 
| At this point it accepts single striking the characters in the
| user name, but the "Password:" prompt never appears.  I finally
| get:
| 
|   Login timed out
| 
|   Wait for login exit:
| 
| after which the screen clears, the initial "login:" prompt
| reappears, and the cycle repeats itself.
| 
| If I press [Enter] before seeing the "timed out" error message
| I simply get another "login:" prompt.  Entering the user name
| at it evokes the same behavior as did the previous instance.
| 
| I verified for myself that 'getty' is accepting the user name
| properly (whether entered with single or double key striking)
| by executing this script while trying to login on tty01:
| 
|   #!/bin/ksh
|   while :
|   do sleep 1 ; date ; ps -ef | grep console | grep -v ttyp4
|   done > /tmp/report
| 
| and seeing these (edited) results in the output file:

|   Sun Nov 12 09:47:45 EST 2006
|       root 19067   1  0 09:47:29 console   00:00:00 /bin/login root
|   Sun Nov 12 09:48:46 EST 2006
|       root 19456   1  0 09:48:46 console   00:00:00 /etc/getty -n tty01 sc_m

| The SCO Knowledge Base offered no help.  Can YOU help?

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission.
