| Tests that a cellular modem is available for testing. |

| The test attempts to detect the modem state by running the modem status |
| command on the DUT and strips the state from its output. The test saves the |
| original modem state and reboots the DUT regardless of what state the modem |
| is in. After the reboot, it tries to get the modem state again and if the |
| modem does not respond or the state is one of the following as listed below, |
| it tries to reboot the DUT for a maximum of two tries by default. User can |
| override the number of tries by passing a tries flag with a desired value. |

| the servo.): |

| GOBI MODEM STATE DISCONNECTING = 70 |
| |
| WAIT DELAY STATES (Waits for a maximum of 120 seconds for the modem to get |
| into a testable state. If the modem is still not in a stable state after the |
| first try, DUT will be rebooted.): |
