Using serial port of a rep3440 to connect to the console of another rp3440

Hi

I have two rp3440 boxes. One of them (call it A), is properly installed and configured. The other one (B) is not installed nor LAN console is configured. The only way is to attach a based-character terminal (or a PC emulator) to the console port, but I have no based-character terminal.

I have a MS-Windows XP laptop: 1 GB RAM, a Dual Core,... and all serial ports are USB.
I have a USB-to-Serial converter but the connector is a DB9 male (the connector of console cable is DB9 male too)...

No problem: I also have a null-modem cable (DB9-female to DB9-female). The final mess is:

(laptop USB)----(DB9-male):(DB9-female)---(DB9-female)(DB9-male)---(DB25-console)

--- means cable
: means connection

But that doesn't work. I cannot connect to idle box (B) NOR running one (A).
Line settings are according to "rp3440 Installation guide".

The last idea is to connect from serial port of box A to console connector of box B.

Is that possible? The three serial ports for console in a rp3440 are tty1pX ?

Thanx in advance

Yes, that is possible.

You must connect from the Remote port of box A to the Console port of box B. The Remote port seems to be /dev/tty1p2 according to my notes.

You can use the HP-UX standard command "cu" to access the console of box B through the cable.

You must first add a line to /etc/uucp/Devices, like this:
Direct tty1p2 - 9600 direct

After adding this line, you can connect to the console of box B with:
cu -l/dev/tty1p2

To disconnect the cu connection, type the escape combination , or "~."

This is similar to the force-disconnect escape key for SSH, so if you're using SSH to connect to box A, type "~~." instead.

If this is a new box, the default network setting for the MP is DHCP.

The name is mp+MAC address, like mp123456789abc.

Try to find the addresslabel on the box and connect to this name.

Hope this helps!
