Hi, I have a Siemens BS-11 with the factory cable for the LMT that has a DSUB-9 plug on the non-BTS end. When I connect a USB<-->RS232 adapter and run either $ cu -l /dev/ttyUSB or bs11_config -p /dev/ttyUSB0 I do not get any output when I switch on the BTS. I tried with nullmodem adapter and without just to be sure since I often mix up the pinouts. I was not able to measure any voltage on any of the DSUB-9 pins when the BTS is powered up, but believe that on either RX or TX there should be the voltage level of the serial line since RS232 is active low. Has somebody seen this behavior?
