I killed it with signal -9 and tried to connect with cu: # cu -l /dev/cuaU0 -s 150200 connected but it doesn't response. At this very moment, how could I determine if there is a problem with the modem or with the USB port/bus? My only choice now is to reset the USB port with usbconfig -d 0.2 reset. Thanks in advance Regards Alberto Mijares
