If I recall correctly the Operations Console that used the serial port was
based on a weird TCP over Serial stack. That was deprecated on Win7, so you
need a WinXP machine, with a serial port, with the time-period correct
Client Access and even then the thing was extremely finicky, I remember
several days fighting the console and the 25,26, 65+21 functions to get
back the console, but that was on Power5 hardware. I have never seen a
non-twinax machine before the Power5 generation.

Hi Marc,

Thank you for taking the time and researching all this :)


I was looking for information about LAN console and 170 models, as I am
quite sure that, unfortunately, it does not apply. But, I have found the
original IBM documentation about Operations Console which applies to a
170. The book reference is SC41-5508.

You can read it a pretty applicable version (May 2000) here

I took the time to go through your emails, especially the last one you
sent about the 2721 card and ops console cables, and I think I got some
interesting info with your aid:

I definitely have a 2721 card on slot C08 (although it doesn't say 6A59),
DSPHDWRSC says:

LIN01 2721-001 Operativo Adattatore
comunicazio
CMN01 2721-001 Operativo Porta
comunicazioni
CMN02 2721-001 Operativo Porta
comunicazioni

Nome risorsa . . . . . . . . : CMN01
Testo . . . . . . . . . . . : Porta comunicazioni
Tipo-Modello . . . . . . . . : 2721-001
Numero seriale . . . . . . . : 53-8304072
Numero parte . . . . . . . . : 0000021H5386

Ubicazione fisica:
ID segmento 1
Posizione schede C08
Indirizzo logico
Bus SPD:
Bus di sistema 1
Scheda principale di sistem 0
Scheda di sistema 1
Comunicazioni:
Bus I/E 14
Adattatore 1

So ideally I should be able to connect via Client Access using a 97H7557
operations console cable, connected to one of the 2 2721 ports.

All the pieces fit together, now I just need to find that cable :)


Thank you again!
