console output ?

[Michael Kraemer]

hello group,

I've a stupid question concerning console I/O after installation
(yes, I've googled this newsgroup, without success).
Recently I've installed a p630 with AIX 5.1 using an ASCII terminal
connected to the serial port. All went well until after installation,
from this point console input was no longer possible. The terminal
itself seems to work (cross check with another machine).
Do I have to specifically enable login (active only after reboot)
or is there some other method (I'd rather avoid reboot, since lengthy
production jobs are running) ?
Is this a new "feature" of 5.1 ? Comparison with older machines
allowing console I/O do not show apparent differences in console I/O config
and tty settings.


TIA

As a standart answer I would say, it's a problem with your terminal connection
Installation (and boot screens) just work with a 3-wire serial cord (Rx-Tx-GND),
but AIX (and getty!) like RTS/CTS and DTR/DSR being connected as well, so you
need a more elaborated cord to connect your ASCII terminal.

I'm not understanding well. Can you see anything on the console, or
are you saying the console keyboard input doesn't work?

Ha the classis cable problem. A regular console cable will allow you
to install and run in maintenance mode but will not let you login once
the OS is installed. I had the same problem with my 630. The pinout
that will allow you to do everything is:

DB9 Female (DTE) DB9 Female (DTE)
3 XMT or TD -- 2 XMT or TD
2 RCV or RD -- 3 RCV or RD
7 RTS -- 8 CTS
8 CTS -- 7 RTS
5 GND -- 5 GND
6 DSR -\- 4 DSR
1 DCD -/
/- 6 DCD
4 DTR -\- 1 DTR


This can be used to connect the 630 to your PC on a DB9 port, use
Hyper Terminal (or other terminal soft).

ciao, Nic.

OK, maybe I was a bit fuzzy on that, it's showing "some" output,
although in a "corrupted" manner, looks like a '\n' is missing.
It doesn't allow input.
As said, terminal has worked when connected to e.g. a running 44P/270

Is that specific to a 630 ?
I'm using an IBM ASCII terminal rather than a PC, does that make a difference ?

No, I've had it e.g. an a 43P-150.

No, not the terminal is the problem, the AIX software want's to have
hardware handshake.

Nope, it's the same pinout for all IBM RS/6000 systems (well the ones
I used, dates back from AIX 3.2 days).

No, it does not. A null-modem adapter pluged in your cable can also
do the trick.
