Computers, terminals, modems, and printers were once connected in a system using RS232 serial ports. That use-case is obsolete and the Ports of minicom and picocom are unmaintained but there is still a use-case. For example, in a factory, simple controllers, widely placed, can be wired into a system computer via RS485.</div><div><br></div>I would like to use picocom with DragonFly.
