Default serial console login problem

Hi,
I have 2 p520 server. First server, I can use my null modem cable to
connect between my PC's serial port to the p520 serial port one. I get
the boot screen and I can install the OS in there. Finally, I get the
login prompt from the PC's Hyper Terminal. But the 2nd server is
strange, I get the boot screen. However, the screen stop at the
"Starting AIX software", I can't get any login prompt so I can't login
the server successfully.

Any special configuration in the ASMI I need to setup?

P.S. My HyperTerminal setup is 19200-8-N-1

After the "Starting AIX software" try moving
the cable to serial port two (if there is one).

Also try 9800-8-N-1

Try a service mode boot and set the console to the current terminal...
if it has a graphics card in it, or a kbd/mouse hooked up it will
ignore the serial port

i have the same hyperterm setup and it usually works fine. I have had
to switch the cable to the second p5 serial port to get a console. Not
sure what would cause that, but it had me stopped cold until I stumbled
onto it.

The port (most likely /dev/tty1 is NOT enabled for login or NOT the
assigned console.

In maintenance mode (however you get there) key "chdev -l /dev/tty1 -a
login=enable" or "chcons /dev/tty1".

That should get the action you are expecting.

Good luck.
