Using a different /dev/console

Greetings--

I have a pair of boxes that I'm using for kernel development, and I'm trying to get kwdb, the kernel debugger, working.

Since I have 2 asio serial devices, I thought I would be able to use one of them for the debugger. However, the first is used as the console, and the second does not have a serial connection -- it's an integrated web console with only a lan interface. I'm fine using the web console as my console, so I'd like use the asio device at 0/0/5/0 for console, so I can use the one at 0/0/4/0 as a serial device.

When I connect to the web console at 0/0/5/0, I can talk to the GSP, but I cannot gain access to the console. I assume that is because the console is configured on 0/0/4/0.

So, How can I configure my box to use the asio device at 0/0/5/0 as the console and the one at 0/0/4/0 as plain serial? Or, is there an easier way of getting kwdb up and running (I don't have an extra LAN interface to dedicate, and I need access to the network interface while debugging, so I can't dedicate my only interface to kwdb).

Thanks.

Re: Using a different /dev/console

You can have them both hooked up but there is a key sequence to toggle between the lan console and serial console. I will have to look for that sequence. Let me look around.
