Hi Christopher,

thanks a lot for the info.

I've jJust knocked a cable up using  a patch box and still no joy - looks like the switch may be faulty - it just refuses to talk to Hyperterm.

I'll keep at it, but I'm not hopeful,

regards

Dave

Dave,

Very nice! I have not seen a breakout box in years. I must admit, I'm a little jealous. Please be sure any adapters being used are straigh through with your VOM.

The next part of the equation is that you must set your hyperterm connection up for this device. I should have mentioned this earlier, but I certainly did not suspect you would have access to a "cable" that fast. Set your line speed for 38400 8,N,1 with no hardware flow control. Please be certain that you are using the correct COM port, and that it does in fact work.

Keep me posted,

Christopher

Christopher,

mmm, I think I'd much rather I handn't seen one too :-)

Thanks for following this up.

Still no joy, I did have those comms settings (I'd downloaded a copy of the manual). I have powered the switch off/on a number of times, hitting "ESC" at various points, but am still not getting any response from the switch,

Dave

Dave,

The console port speed can be adjusted. Let me get one in my lab and check the available speeds. Chances are good that if someone did change the speed, they went for the maximum. Although, if there was a problem with the speed, you would see gibberish instead of nothing. Makes me wonder if there is a "wire shark" for com ports.

Chris

Thanks Chris,

I had not thought of even trying that - as you say, most people would go for the fastest.

Off to play with the baid rate just in case . . . .

Regards

Dave

Dave,

Those speeds are 2400, 4800, 9600, 19200, 38400, 57600 & 115200. I would start with the 115200.

Hi Chris,

thanks a lot for the info, I've tried all those, still no joy I'm afraid.

Not that I think it's going to matter, but protocol are you using ?

regards

Dave

Dave,

VT100

OK,

thanks Chris, that's what I'd tried. I guess that was the last throw of the dice !

Looks very much like I've got a broken switch !

Thanks very much anyway,

regards

Dave
