The easyiest answer is get the hardware refernece library and look it 
up. the RKM is a godsend, but heres what you need to do :)

	Peek the value at $BFD200 - the direction register for CIAB
	Bset bit 7 of the value
	Poke the value to $BFD200 - 
	
	Peek the value at $BFD000 - the data regiuster for CIAB
	Bclr or Bset bit 7 of the value
	Poke the value to $BFD000

	Err.. That should do the trick...

	Some extra info for you boffins out there..

	Address  Bits 7   6   5   4   3   2   1   0
	$BFD000      DTR RTS CD  CTS DSR SEL Pout Busy
	$BFE101      parrell port raw data
	$BFD300      direction: 1=output, 0=input
	$BFE301      direction of each bit of parrell port,

	Hope that helps, If not get back to me.
