Summary: pull out/put in GUI console won't reset console hung by SAM

Thanks to all who responded, esp Mr Mueller for the patience
& responses again & again.

We don't have any other accounts to access the system at
command line, both oracle & root have been disabled.

Actually, at the console, if we click "" to switch to
"Command Line login", root can still login though it's disabled
& after tt all we need to do to enable back the accounts are:
"/usr/lbin/modprpw -k root"
"/usr/lbin/modprpw -k oracle" or
to null the passwords (if we've forgotten the passwords) :
/usr/sam/lbin/usermod.sam -F -p "" root
/usr/sam/lbin/usermod.sam -F -p "" oracle

Having lost the above chances as SAM garbled the screen
(& we press more keys to complicate it, <Tab<Enter>
DownArrow key twice <Entershould have exited the
garbled SAM for us but we messed up this chance)

The other chance was to use MP login as Admin, choose
C & press
Press Control + Shift + e (then release all keys)
Press c (release)
Press f

We lost this chance too probably SAM garbled the console GUI

So finally to login to MP, choose CM, choose RS (reset) at
menu below

MP MAIN MENU:

C: Console
VFP: Virtual Front Panel
CM: Command Menu
CL: Console Log
SL: Show Event Logs
CSP: Connect to Service
Processor
SE: Enter S Session
HE: Main Help Menu
X: Exit Connection
