How to Check for Faulty Modems or ACUs

You can check if the modems or other ACUs are not working properly in several ways.

  1. Become an administrator.

    For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .

  2. Obtain counts and reasons for contact failure by running the following command:
    # uustat –q
  3. Call over a particular line and print debugging information on the attempt.

    The line must be defined as direct in the /etc/uucp/Devices file. You must add a telephone number to the end of the command line if the line is connected to an autodialer or the device must be set up as direct. Type:

    # cu –d –lline

    line is /dev/cua/a.
