Re: ppp mystery



Thanks for the advice. It worked like a charm. I don't know why I hadn't thought of it earlier. I tried Isolating the one setting which is crucial that the modem received in Windows and not
in Linux and found out it was AT&B1 which manages the modem's serial port rate.
&B0 means variable, follows connection rate
&B1 means fixed serial port rate
&B2 means fixed in ARQ mode, variable in non-ARQ mode.

I guess the port rate needs to be fixed.

Thanks a lot

Gil,

I had a very similar problem with my US Robotics V.Everything external
modem.  This may sound insane, but my problem seemed to be related to modem
initialization strings.

There is a setting someplace in Windows for its dialer that makes it create
a log file when it dials the modem.  One of the things that it puts in the
log file is the initialization string that it sends to the modem.  I'm
sorry, but I forget exactly where the setting is (I have been using DSL for
some time now and my modem is gathering dust on the shelf  :-) ).  Look
through the properties for your dial-up connection.  I believe that the log
file is created in the \windows subdirectory.

The way I got it to work with my modem was to take the modem initialization
string (it starts with AT and has a bunch of letters and numbers and symbols
like "&", "%", #"  in it - please forgive me if you already knew that :-) )
from the log file and plop it into my wvdial configuration file so that it
used the exact same initialization string as Windows.  There might be more
than one line in the log file.  Check the wvdial documentation for more info
on how to modify its configuration file if you're not sure.

That might not be your problem, but it was what worked for me.

As an aside, I believe that whether you need to use PAP or CHAP is
determined by your ISP, not Windows.  I believe that most of them use PAP,
though.  I could be mistaken.

I hope that helps you out.

Best regards,

Tom Delany
