Don't try this at home kids !!!!!!!!!
NO ! This can't work !! The printerport is as parallel port and not a serial
port.
The availablity of the IR-tower is checked by using the serial handshake line.
This can't work with printerport !

I don't know a printerport to serial adapter till now. Please tell me were you
found such think.

YES, this shouldn't make a difference, because both the 9pin male and the 25
pin male are serial ports. But the 25 pin female is not !

I don't know if you can break your hardware with this, but I wouldn't try !!!

NO ! When using an adapter be sure it has holes at one end and pins at the
other (25 -> 9 or 9 -> 25)! Everythig else makes no sense !!
Everyone who isn't sure should have a look at
