Trouble getting serial output from Ultra 10

Iam trying to get make a serial connection to an Ultra 10 from my laptop. I've set the output to goto ttya in the nvram parameters. Iam using a db9 converter at the laptop end and a db25 converter at the ultra 10 end-I know the adapters are fine and so is the cable. Iam just not able to get it out on hyperterminal (Default settings-baud-9600). Am I doing something wrong here?

Thanks !!

I believe that powering up an Ultra 10 with a keyboard and monitor attached will disable the serial port. The Ultra 10 only supports a single console i.e. serial or keyboard and monitor.
