Enablement is done on a Module + System basis. **Systems not listed 
are currently not supported.**

------------------------------------------------------------------------
Tested Operating Systems:
- Ubuntu 22.04 : OK
- Fedora: OK (Not tested for RW101 and Foxconn SDX61 modem)

------------------------------------------------------------------------
**Please follow the procedure below step by step to enable WWAN**

1) Run the `fcc_unlock_setup.sh` script to
   install SAR config package and FCC unlock:
   ```
   chmod ugo+x fcc_unlock_setup.sh
   ./fcc_unlock_setup.sh
   ```
2) Reboot machine (Only needed once)

------------------------------------------------------------------------
**Please follow the procedure for uninstalling this package**

1) Run the `fcc_unlock_uninstall.sh` script to
   uninstall SAR config package and FCC unlock:
   ```
   chmod ugo+x fcc_unlock_uninstall.sh
   ./fcc_unlock_uninstall.sh
   ```
------------------------------------------------------------------------
Logs can be checked using **one** of the commands below:
- For FCC Unlock: `cat /var/log/syslog | grep -i DPR_Fcc_unlock_service`
- For SAR Config: `cat /var/log/syslog | grep -i configservice_lenovo`
- `journalctl`
- Please follow below steps to enable **Verbose** logging:
  1) **For FCC Unlock**:
  Add "-v" in FCC unlock scripts updated in "fcc-unlock.d.tar.gz", for example:

FileName - fcc-unlock.d/8086:7560
  
      Modification- "./opt/fcc_lenovo/DPR_Fcc_unlock_service **-v**"

2) **For SAR Config**:
      Add "-v" in systemd service file, for example:

FileName - lenovo-cfgservice.service
  
  Modification- "ExecStart=/opt/fcc_lenovo/configservice_lenovo **-v**"

------------------------------------------------------------------------
Additional Notes:
- If the Modem disappears after the machine reboots, please
restart it with the `systemctl restart ModemManager` command.

- WWAN enablement is currently blocked for the USA SIM, as carrier certification 
for Linux is not being pursued at this time. However, I will provide an update 
if the situation changes in the future.
