[En-Nut-Discussion] Problems with ppp and gprs modem TC45

[Cosmin Buhu]

    I was using a Siemens C55 as a modem, I think is not much different
firmware wise, at least in GPRS features; I haven't any problem with it.
    Can you see PPP negotiation phases on the serial link, are you able to
catch/study them?
