===== Javad =====

  * Configure the receiver to put out the GPS GGA message over the serial port A

==== Serial Port Adapter ====

I had this same problem outlined here:  [[https://forum.manjaro.org/t/modemmanager-mobile-broadband-adapter-not-supported-anymore/45268]]

Trying to use a [[https://www.tripplite.com/keyspan-high-speed-usb-to-serial-adapter~USA19HS|Keyspan 19HS USB to Serial adapter]]

  - Create this file for the modem manager
    - Edit this file <code>
sudo nano /lib/udev/rules.d/78-mm-whitelist-internal-modem.rules
</code>
    - Put these contents in it <code>
ACTION!="add|change|move", GOTO="mm_whitelist_internal_modem_end"
    ATTRS{idVendor}=="06cd", ATTRS{idProduct}=="0121", ENV{ID_MM_DEVICE_PROCESS}="1"
    LABEL="mm_whitelist_internal_modem_end"
</code>
  - Restart the service <code>
sudo udevadm control --reload
sudo udevadm trigger
</code>
  - I ended up rebooting but probably wasn't nececssary

To talk to the javad <code>
sudo minicom /dev/ttyUSB0  # should not need sudo to do this if in correct group
</code>

I also added **hdl** user to the dialin group with the following command
<code>
sudo adduser hdl dialout
</code>
  * **libserialport** <code>
sudo apt update
sudo apt install libserialport-dev
</code>
