2 . Try to start them again: cyclades-serial-client start Messages: "cyclades-serial-client : /dev/ctty01 already active" "cyclades-serial-client : /dev/ctty02 already active"

3 . Stop only /dev/ctty01 device: cyclades-serial-client stop /dev/ctty01 Messages: "Stopping /dev/ctty01 <==> pr3k:2 interface"

4 . Checking status: cyclades-serial-client status Messages: "/dev/ctty01 (rtelnet at pr3k:1) is inactive" "/dev/ctty02 ( socket at pr3k:2) active, pid 2983"

5 . Start a non-valid device cyclades-serial-client start /dev/xtty01 Messages: "cyclades-serial-client : device /dev/xtty01 does not exist"
