No Modem Manager or anything else using the /dev/ttyS0. I thougt this setting has something to do with flow control (RTS / CTS) and that it had to be turned off because these pins are not used / connected.

There are some 'send timeout' messages with ''blazer_usb -DDDDDD -a myups -x subdriver=phoenix'. Is this of any importance?
