Serial console on RS6000 1

[strider952]

Hi all,

I have several RS6000 systems I would like to connect to my terminal server. For those who don't use one, a terminal server takes the serial consoles of systems and allows you to telnet into them. Saves a lot of space (and walking!)

I've connected up my Intel, Sun and HP systems with no problems. The AIX systems have been difficult. Right now they have IBM3151 consoles on them, and they work fine. However, when I connect up to my term server I get console output but can't type anything.

Any tips on what "smit tty" settings I should use? Term server settings? Do I need a special cable? I notice that all my consoles have this bizarre cable arrangement coming out the back. The cables are unlabelled, of course, so I have no idea if they're straight-thru, null modem, or something else entirely.

Any help would be appreciated!

9600 8n1

and specify correct term (most likely not ibm3151 anymore - but vt100 or vt220)

Thanks for the quick reply. I tried vt100, still no luck. Any idea what flow control to use?

More weirdness....

When I reboot the system I can get into and manipulate the SMS system fine. It's when it switches over to the console that I lose the ability to xmit. And yes, I have "Enable LOGIN" set to "enable".

I imagine that adding clocal to the end of STTY runtime and login might help?
go to those lines....arrow to the end of each line, put a , and then clocal....
Not sure it will work...might............
Also how it is wired makes a difference as well... hardware flow is the best, but not sure if your terminal server handles it or how many pins or even if it is cabled right...
Try the clocal...

Oh you might have to mark the last line of that screen...add to database only to yes...since you might get device busy if you don't. It will take a reboot to make it active.

Setting a tty

When a tty is set in SMIT, the default TERMINAL type is "dumb".

Example:

BAUD rate [9600]
PARITY [none]
BITS per character [8]
Number of STOP BITS [1]
TIME before advancing to next port setting [0]
TERMINAL type [dumb]
FLOW CONTROL to be used [xon]

STTY attributes for RUN time [hupcl,cread,brkint,icr> +
STTY attributes for LOGIN [hupcl,cread,echoe,cs8]

flow control XON/XOF== Hardware

WTG aixqueen and gheist! Your suggestions worked.

Thanks, this makes my life MUCH easier (and my
lab MUCH less cluttered!)
