The Point to Point Protocol (PPP) network interface lets you set up a network connection over a serial link to a remote network stack. An additional module (PPP over Ethernet or PPPoE) is required to run the PPP module on an Ethernet network.

The PPP module is part of the HCC MISRA-compliant TCP/IP stack and is designed specifically for use with it.

The Networking Overview diagram shows the three main PPP components:

  • The PPP interface.
  • The PPP over Ethernet (PPPoE) module.
  • The PPP low level driver – this implements a serial driver for the HDLC framing protocol specified in RFC 1662 and used by the PPP implementation over RS 232.
  • Conforms to the HCC Advanced Embedded Framework.
  • Compliant with the HCC MISRA TCP/IP stack.
  • Designed for integration with both RTOS and non-RTOS based systems.
  • Compliant with RFC 1662.
  • Support for up to four PPP interfaces.
Configurable Options
  • PPP configuration options.
  • Challenge Handshake Authentication Protocol (CHAP).
  • IP Control Protocol (IPCP).
  • Link Control Protocol (LCP).
  • PPP Authentication Protocol (PAP).
  • Van Jacobson (VJ) compression.
  • Serial driver.
