[En-Nut-Discussion] PPP Debugging Software

[Ahmad EL Hakim]

First time to list.

I am e-mailing regarding the above subject. I need to read the PPP packets
on my dialup modem as I have problems with my connection (always gives an
error while registering the computer after modem negotiation). I am
suspecting errors in the LCP or IPCP, so I need to monitor the PPP packets.
I have found on the list the below mail, so can Louis send us the steps to
capture the PPP packets and the app he mentioned in his e-mail

Best Regards,
Ahmad EL Hakim

Hi Mike,

I would love to get that serial port monitor program.

I played around with Ethereal, and made a function to print out received PPP
data to the debug port.  There's an app to convert raw data to the form
Ethereal understands.  It's not as streamlined as it could be, but takes
less than 30 seconds to do.  I'll make a short list of steps and post it to
the list later.

Thanks,

Louis
