Check out the RIL and how this handles the modem and allows you to make a PPP connection and then use TCP/IP as you would with WiFi.
The best way to use a modem is with USB as this allows the RIL to do PPP over one connection and monitor for SMS etc on a second connection. If you have a single UART modem, you will need to implement the CMUX protocol to be able to have simultaneous ports. I am not familiar with CMUS so I used a SIM7100E modem with USB port to connect to Android 5.1 and later 8.1 using the RIL supplied by SIMCOM. If you can find a modem manufacturer who offers a RIL for your modem, the easier the integration will be. Good luck.
