Hi,

The speed is 9600. Actually I already tried with 7.1-RELEASE, with same results.
I'll try the device.hints-changes, thanks.

Is the application fairly low speed (e.g. 9600bps or slower) ?  If 
so, try with 7.1R, not 7 and add

hint.uart.0.flags="0x100"
hint.uart.1.flags="0x100"

to /boot/device.hints
