While I agree with you in fact, in principle the gameport I/O
(annunciators/pushbutton inputs) are capable of serial I/O at 57kbits/sec
and, with appropriate protocols (NadaNet) more than twice that.
Communication with a modern computer would require UART-like serial (due to
limitations of the modern PC, not the Apple II ;-), and so would be limited
to 57kbits/sec.
