Not under linux but I cant find a better place to ask serial questions, and it is for a bootloader for linux :-) I've managed to get the PXA2xx serial port up and running, and can see the IrTX LED light up on my digital camera, so I know the transceiver has power. Further, I can receive data, however it is _all_ zeros, no matter what the host transmitted. I cant see how this is a problem with the transceiver as I would have thought this would have resulted in me seeing no characters at all. It would be helpful if I had some way to snoop the hosts serial port, as I cant find a way to get the linux IrDA stack to show me the raw data as it arrived at the serial port (its a SIR dongle, so I cant just read ttyS0). irdadump is great but only shows valid packets, not the raw data.
