According to this webpage, [http://www.systemed.net/pcw/cps8256.html], the Cirkit serial interface uses the same Port addresses as the Amstrad / Pace interfaces (most information on that webpage, especially the clock frequencies, baudrate, and chipset, seems to be incorrect, so not too sure if the part about Cirkit I/O ports is correct).
