Thanks a lot for the information :) I will need, for sure, at least this card: http://www.dialogic.com/products/serial_protocol_adapters/Eiconcard_C_Series.htm?techspec=1®ID=4599 But I don't really know what the driver does. I will use it on QNX (yeah, I know it wouldn't be hard real-time :)), so it's not the driver/software it says there. It's this one, in case it matters/gives anyone some idea: http://www.gandacar.ca/index.php?option=com_content&view=article&id=60&Itemid=89 I think that this card does almost everything in hardware and the driver only does some communication (although I don't know how) Have anyone used this card with passthrough or have some intuition if it should work ? :) Thanks a lot, Rodrigo -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
