The thing is that the IRDA-tranciever I use does disable the reciever "eye" when transmit, that´s hard coded. But I desn´t need to be a problem.
If just FLIP could support Half Duplex, that´s it I think.

Bcause with flash Magic ( Philips )I almost get it to work with the ATMEL , but NOT 100% Because of some differences between them. BUT without the Half Duplex Mode Enabled , it won´t work at all. - So Half Duplex Mode in the PC seems to do it...
