PPP setup

I'm attempting to get PPP working. I have a socketmodem connected to an LPC2468 on uart 1. have the serial driver working.

Do I need to include Std_Modem.c in my project?

Where do I make changes to support my particular modem?

I'm not finding this obvious.

  • Same problem but dropping a ~ every 2 do not work
    properly.
    I push a dummy ~ as the very first char in the RX buffer.
    It seams that there is an unalignement in the PPP framing
    scheme.
    My app works like this:

    ~~FRAME~~FRAME~~FRAME~~......
    the first ~ is dummy

    My app do not works like this:

    ~FRAME~~FRAME~~FRAME~~......
    dropping every 2nd ~ the PPP still goes up with lot of
    retrans but then for example if you ping the board it
    responds only to even icmp packets (PPP decodes 1 frame
    every 2).

    let me know your opinion.
