Consoles

[Duncan Morris]

Wim,

have you tried shifting the console manager to another port? It might be that Transmit is down on the port, but Receive is still ok.
I have had that on old DECserver systems.

[Wim Van den Wyngaert]

Duncan,

You mean another decserver port ?

[Duncan Morris]

Yes Wim. Sometimes they fail permanently, and sometimes they seem to get into a hang state. That was my experience of console manager with DS550 servers. They sometimes cleared after a decserver reboot - but that affected 100+ users at a time.

Perhaps you should disable flow control on the decserver port to which your console port is connected?

That's how I run ours. Long ago, with older versions of Vaxcluster Console System (as it used to be called), I think I had a problem with flow control hanging things up, but my memory could easily be inaccurate.

Galen,

NO results. I compared with another alphastation 500 also beeing monitored via console mgr (but one that works). Identical decserver port settings.

If you have physical access to the machine, it might be easiest to disable the boot disk (either unplug it or just unplug its power source) and then power up the box; the auto-boot should fail and it should then drop back to console mode.

You should be able to get a >>> prompt on at least one of the serial ports on the back of the machine at that point, and when you do, do the command:
>>> SET CONSOLE SERIAL

[Wim Van den Wyngaert]

Keith,

Indeed. Just a pitty that nothing is foreseen to still capture the control-p.

Btw : I connected a console and set console to serial. But I now noticed that it didn't boot in graphical mode (no log files) until I connected the screen. Strange.

Hi Wim,

When you connected to system using console manager, what you get when you type SHO TERMINAL ( OPA0: or TTA0: ...) . It should be OPA0:

Thanks & regards,

Wim,
are you sure of using CTS/RTS signal? For theese signal you need a full cable and they aren't right managed by OpenVms; I guess is bettere disable CTS/RTS and holding DTR/DSR.
