  Hi !

Anyone tried to use the IrDA port of the Rev. A+B iMacs?  According to the
IrDA people I should see some packages coming in if I look at the port
while some other IrDA device tries to connect.  But I see nothing with

The IrDA port is /dev/ttyS1, the device-tree entry looks like this:

/dev/ttyS0 (the buildin modem) works fine with minicom.  Any hints where
to look / what to check?
