I had such a configuration a few days ago. 7200 -> ix86 with a usual modem cable. You need a kernel with support for PowerMac serial port and console on serial port. Then give the arguments like described in Documentation/serial-console.txt : console=ttyS0,19200 and you will see an output on your console and the penguin on your screen. It should be possible to log both to serial and to the screen. For a first test you should setup a serial login to check the settings in zterm. Add a line like this in your inittab: t:23:respawn:/sbin/agetty -L -h 19200 The 23 mean the runlevels and might be different on a RedHat system. If you can login to your 7200 then the cable and the settings in zterm are ok. Somehow you always get a little garbage when you login from a Mac to another Mac. This does not occour from a ix86 machine, I don't know why. Gruss Olaf -- $ man 1 current_release BUGS Users never read manuals... ** Sent via the linuxppc-dev mail list.
