You'll find info on Pi Doors here (Agency) posted multiple times by various people to this area (Mystic BBS Support). Use T for search and Doors. As you walk though Mystic BBS support searching for doors you'll find all kinds of information in this FSX_MYS area. There are two main Pi Door setups:
qemu setup & DOSBox setup. Gryphon was the first to write up using qemu with FreeDOS image. It will work on Pi B on up. Faster newer Pi can use DOSBox. Gryphon's method was based on a couple of older setups: https://en.wikibooks.org/wiki/QEMU/FreeDOS http://how-to.wikia.com/wiki/How_to_install_FreeDOS_in_QEMU

To get things from here on most Pi you open another Shell (Control-T) and use the mouse to highlight areas, then Control-SHIFT-C to capture and Control-Shift-V to paste. That should work in both directions.

... Everyone smiles in the same language.
