I recently purchased a US version of the Alcatel Minitel terminal. I think it's a 1B version. Pictures of it here:
I tried connecting a null modem to the 25 pin port on the back and plugging it into a linux box running agetty but I couldn't get it to show any signs of being connected. I used Google Translate to translate this document into English: http://mirabellug.org/wikini/upload/Documentations_minitel.pdf
As far as I can tell, you take it out of videotex mode by typing Fcnt-T A, then turn off local echo with Fcnt-T E, then set it to 4800 baud with Fcnt-P 4. I presume Fcnt refers to the "CTRL" key on my terminal. But I think I'm doing something wrong, because it doesn't look like it's recognising the keystrokes, because "Fcnt-T A" just prints the letter A to the screen, which is not what you'd expect a function key combo to do.
Has anyone used these minitel terminals as a linux terminal, and if so, please can you share how to configure the minitel to run as a terminal ? Is the 25 pin plug even the correct port to use ? I read something online that indicated you're supposed to use the 5 pin DIN plug instead, is that right ? If so, what's the 25 pin plug for ? If I am supposed to use the DIN plug, does anyone know the pinouts so I can make a cable ?
