Hi. FYI. Have tested the bcmxcp driver from cvs development tag. And it work as expected on the 5115 with the serial interface. So to Wolfgang, no bug introduced in the serial module when you split'ed the driver. If i get some time to spare, i have a look on the serial module to make it wake up the ups. The 9125 is type pnp so it need to be waken up. Then there are some cleanup to be done to the code. Kjell
