    wvdial problem: is this a line termination issue?

    Hi all,

    I'm losing my mind trying to fix this problem, perhaps one of you kind sirs/madams could help me out.

    Problem is this, I running a 2.6.35 kernel on an embedded platform and I am trying to connect a GSM modem to the board.

    I can talk to the modem using microcom, send 'AT' and that, however I must make one change to receive the 'OK' reply, the change is that I must set 'NL to CR/NL mapping' within microcom.

    Now when I try to run wvdial I get the following

    # wvdial
    --> WvDial: Internet dialer version 1.61
    --> Initializing modem.
    --> Sending: ATZ
    --> Sending: ATQ0
    --> Re-Sending: ATZ
    --> Modem not responding.
    Now I may be wrong, but I am assuming that wvdial is not receiving the 'OK' prompt (similar to microcom before the setting change) from the modem because of the NL CR mapping? Which I cannot change in wvdial.

    Is there are more 'global' way of changing this CR NL mapping in the hope that it will fix my problem?

    Oh yeah, I have tested my wvdial configuration on my desktop and it works ok.
