        Looks like one that requires a mode switch of some sort possibly? Or otherwise maybe not choosing the correct serial port. The chosen port has nothing answering on it.

          for some reason more serial devices popped up in the selection window.
          but still no connection.

              cuau0 is your onboard COM1 serial port. That modem device would be cuaU something.

                ^that

                Plus, to exit cu when it appears "frozen", press [Enter] Then type "~."  (without the quotes)

                I seem to recall recently seeing that u3g can only perform its automatic mode switch if the device attaches during bootup, not when inserted after, so your safest bet is to plug the device in, then reboot, and try it again.

                    If it won't boot all the way, you're probably out of luck using it currently. Even if you get it running after (maybe try "camcontrol eject cd1" from a shell) you would have to remove it every time you had to reboot.

                      camcontrol eject cd0
                      Error received from stop unit command

                      (there is no cdrom drive in that computer hence cd0)

                        The error in the original post mentioned cd1, that is likely what the USB modem presents itself as. If it shows cd1 in the console/system log, use cd1 in the command and not cd0.

                        Some of those, when issued an 'eject' command, will switch to modem mode.
