serial console cable specs

serial console cable specs

[Mike Shaver]

I have a DIN<->DB9 adaptor and a DB9 cable, but Something Isn't Right.

I have it set to 9600 N81, and I set console to d2, and I can see the
system menu when the machine boots.  But I can't type anything at it. 
This is making it quite difficult to do anything with my machine, so I'm
going to go get another cable.

What does this cable need to be?  Do I need a NULL-modem thing?  How can
I be 100% sure that a cable I purchase will let my Indy experience the
joys or serial consoling?

And, in the meantime, how can I force my Indy back to console=g?

Mike

The irix man page serial(7) has pinouts for all of the SGI serial ports.
You can view this man page at:

Can't you just telnet in?

man serial under irix will give you the pinouts.

also under irix, you can use the program nvram and do:

nvram console g

or set the environment from within the bootprom.

I have found some terminals (assuming that is what you are using) that
require either DSR or CTS before they will transmit anything even with
flow control off.

No, you see, my problem is that I can't type at the boot prom (busted
cable) or boot the system (autoboot is off, which is usually a feature).
