I'm trying to use an old Commodore 128D as a terminal to access OS X's shell via a serial port. I've used 'screen' and 'zterm' to ensure the two machines are successfully interfaced.

Instructions for opening up the serial console on other Unix-y operating systems don't work with OS X Leopard. My serial port is /dev/tty.usbserial.

* Activating the serial console in /etc/ttys -- No luck

* /usr/libexec/./getty std.9600 /dev/tty.usbserial -- Seem to do nothing

* screen /dev/tty.usbserial -- The Mac and 128D communicate with each other, but a shell is NOT opened on the 128D

I've scoured the internet for a solution to no avail. All I've found are procedues for OS X Server, using SerialTerminalSupport, but I don't have Server.

Any ideas?
