I have 2 Sun Ultra 80's running and I just got a headless 420R that I need to load Solaris 8 on and set up. I don't have an ascii terminal so trying the manuals other suggestion of using TIP to connect over the serial. I followed the sparse instructions (A port of the new 420R and B of the running U-80) and entered "tip hardwire" and get the "connected" echoed, but nothing appears when I power up the 420R. I have tried all combinations of A and B ports on both boxes and changing the /etc/remote file. Can anyone suggest something or must I order a Wyse55? The 420R is first of many and we don't want the cost of a graphics card and monitor.

Thanks,
David

A couple of questions/suggestions:

You could use a laptop to do the install. Hyperterminal works OK for that (In fact, I have one runing right now).

tip should also work for this. You should make sure that your serial cable is a null modem cable, though. (for any connection).

I recently purchased a terminal server (Cisco AS-2511RJ) for console connections (you never know when you will need them) and it works great. I would suggest (even if you don't do it now) that you get a terminal server for when you need to get to the console of the machine.

I know I didn't help much with the tip, but that is a bit of a tricky program for me. Hope some of the other suggestions help,

Things to check:

You need a cross-over cable, but in addition you need (I think), DTR on the 420R side. When the Sun boots headless to an ascii terminal it wants to see that there really is a terminal there.

You probably want to specify the baud rate, data bits, etc., on the U-80 side. Set up a "speed-entry" for this. (see man tip)

You might also check your hardware manual on the 420R for a hardware switch for operating headless. I don't know about that model.

Good luck.
