    Of course it is like USB since the S in USB stand for serial; Universal Serial Bus.

    I don’t remember if RS232 was plug and play or hot swap though. I think you might have had to boot with those plugged in. PS/2 I think you could? And of course USB you can. Good times.

      Yes and no. They could be unplugged and replugged without a reboot. But also you’d have to manually configure the communication parameters of the port. So I hesitate to say “hot swap”.
