Hmm...I did my ZX81 serial port in software! It was only used to
transfer data to the host computer, so it was pretty simple...

You mena it's beyond the ingenuity of these people who connect up
scanners/cameras/LCD panels/... to the ZX81 to add a serial port?
No, no, I meant a ZX81 doesn't have one built in. Of course we use the
Z80A-SIO (and -PIO). Modems were also commercially produced in the
mid-eighties which allowed a simple mod so they could also be used as
serial ports.
