I built a box about twenty years ago to ring a telephone on stage. If you
find nothing better I will try to find the schematic. If I remember

I have some old modems (TRS-80, acoustic and etc.)
which I would like to
use (flashing LEDs are cool) so, I want to build a little telco emulator to
interface with the modems in one of my Linux boxes.
