[rescue] 7043-260 serial console help - no login prompt

[Scott Mickey]

Wise Rescuers, 
I have an IBM 7043-260 (headless), with a 9600-8-N-1 serial cable on tty0. 
Installation of AIX 5.2 goes fine using the serial console, and after 
install I am able to telnet into the box OK.  However, I get no login 
prompt on the serial cable console. 
The terminal server hardware I'm using works OK with all Sun SPARC and 
HP PA-RISC machines, and OK with the IBM 7043-260 during install.  It 
appears the IBM serial port changes it's behavior after AIX 5.2 boots. 
This web page says this is the case, anyway: 
http://www.linuxquestions.org/questions/showthread.php?t=314384
I would like to have login access on the serial port in case I ever 
fat finger an `ifconfig` command and loose network access.  I have tried 
a few things, as shown below, but no success yet.  Your help is much 
appreciated. 

On the console at boot:

-Then no more output, until shutdown.  No login prompt.  No response to keypress. 

If I telnet in, everything is working OK. 
These commands put the word  test  on the console: 
# echo "test" > /dev/console
# echo "test" > /dev/tty0

test

# lscons

# lsattr -El tty0 -a login
login disable Enable LOGIN True

One web page I found says this needs to read: 
login enable Enable LOGIN True

# smit -C chgtty

Changed:
Enable LOGIN  from "disable" to "enable".

# lsattr -El tty0 -a login
login enable Enable LOGIN True

No response to a keypress on the console.  No login prompt. 
Tried changing -clocal to clocal:

Still no response to a keypress on the console.  No login prompt. 
Instead of modifying parameters on the 7043-260, should I be changing 
how `tip` connects to the machine?   My terminal server is a 
Solaris x86 machine with a Digi Xem PCI card that connects to two 
Digi Ports/16em boxes, for 32 serial ports total.   I run 
`tip -9600 /dev/dty/b012s` to connect to the 7043-260 and run the 
AIX 5.2 OS installation.  I believe all RS232 wires are present to 
support hardware flow control.  I am logging into the Solaris x86 
terminal server machine using SecureCRT in vt100 mode.  I selected 
vt100 as the console type during the AIX 5.2 install. 
Any suggestions are welcome.  I will post a summary.

Right, this is exactly what I was expecting to find...  the gfx adapter is a 
1-V (GXT4000P) and the box was running 4.3.3 already.  I'll throw a serial 
cable on it tonight and see what happens.
