The article is here and includes more information than you probably care to learn, but it details the specific entry in the gettytab file to get everything working, as well as adding a few bonuses not covered in the original hint, including transparent zmodem transfers and 57,600 baud operation.
You may want to reference footnote #s 8 and 10 in the article I wrote for on Apple II to Mac Intelligent Serial Terminal File Transfers. I suspect, but have yet to confirm, that the serial terminal support described in this hint can be re-enabled in Leopard and beyond by adding back the required entries in the /etc/gettytab and /etc/ttys files. I realize it's been a couple of years since your comment, but. Enter your login and password, and you're now able to run any command you like! If you use 19200 baud instead, use serial.19200.įinal step: next time you reboot with your old terminal properly connected and configured for VT100 mode and 9600 baud, you should get a login prompt on it. Also, your old terminal should be set at 9600 baud. If someone try this, please post the info here. I don't know the appropriate device for a USB-RS232 interface. Obviously, use tty.modem if you connect your old terminal to the modem port. Edit /etc/ttys with your favorite text editor as administrator to enable login from the serial line - change the line: tty.serial "/usr/libexec/getty serial.9600" vt100 off secureto the line: tty.printer "/usr/libexec/getty serial.9600" vt100 on secureNotes: I use tty.printer, which is the printer port on my beige G3. If you're not the lucky owner of such a machine, you can use a USB - RS232 interface (I do have a beige G3, so I do not have tested this with USB, but it should work as well).īasically, you simply connect the serial connector of the old terminal to the null modem (whose function is to swap transmit and receive lines), then the null modem to the serial connector of your computer.Ĭonfiguration: from the command line, backup the original ttys file by typing sudo cp /etc/ttys /etc/ttys.orig.
The old beige G3 is the only OSX supported computer that have the appropriate built-in serial ports. Hardware: apart from the terminal itself, you need the appropriate type of serial cables (depends on hardware you have), a serial port, and a null modem. It costs almost nothing and is cool, maybe even useful! I use mine as a terminal in a room away from my main computer location, but it could also be useful as a cheap second monitor dedicated to command-line work, to display logs or man pages, or as a jukebox interface in parties to avoid exposing your computer to spilled beer or other liquids (just run the lynx text web browser and some form of web remote control for iTunes).

Old VT-100 serial (RS232) terms can often be found for free in the computer trashes of various institutions like universities.
