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.
