Hooking up a 5-bit Baudot mechanical contraption to a modern OS, even one that is terminal friendly, is not without some challenges: adapting to the non-standard high voltage 60 mA current loop, interfacing ASCII to the much smaller and different Baudot encoding, working in all caps, dealing with Baudot FIGS and LTRS modes, and making sure the computer doesn’t overrun the pokey 45.5 bauds connection. But hey, Unix was developed on (m
