point to point protocol

Our modem using point to point protocol , communicates using the UART interface to the host. what are the steps to get PPP working on windows10 OS.
Is Mandatory to write any kmdf driver for PPP protocol to communicate with my device? or Inbox driver alreay had?
I will register my device with live networks using UART port with AT commands, after that how modem will react as like ethernet adapter?
Kindly explain please
