I agree that this is true. You can get by bit banging a PC parallel port
as an RX01/RX02 because *that* side sets the pace by driving the clock.
With PC parallel port in standard mode, the best you can do is about a
0.5 MHZ clock, 1 uS high, 1uS low.
The RX01/RX02 specs state a maximum clock of 400ns high and 400ns low.
There is just no way to keep up with that clock without some additional
hardware.
