Chris & others,
cg> Yes thanks. PPP ...
Welcome. The notes put some of my Christmas
"break" time to good use.
cg> A problem which rarely occured in the past, now happens daily for me.
Apparently because of telco line degradation.
Chris, could this be a problem with modem
initialization? Have you tested with the
V24 panel as described in my notes? You
might also test with Kermit.
cg> ---- up to here is OK, then the following 2 lines do not occur:
End of script
IPCP is finally ready. Device opened.
Trials against the Vicom router in GulfNet
ended the same way until I discovered the
lack of DNS negotiation. Refer to the
notes on my Web site.
cg> ... further dial-ups fail to dial the modem !!
... the 'system' is caught in an unanticipated state.
... The modem lights react, but no dial tone is available.
So the modem is external. That should help.
I wonder whether the modem simply fails to
get initialized properly again? Also, I still
don't understand very well what happens to a
serial port in this case. PPP.Log should help.
cg> Obviously I've tested several modems and computers and n-o versions.
Good tip. My notes could list specific models of
modems and init strings which have tested OK.
cg> Can someone point me to a broad overview of PPP before I analyse the
RFCs and source code ?
Yes, the RFCs are tough going and I have yet to
find a good overview of PPP. The UBC Bookstore did
not have the O'Reilly book on TCP/IP (ISBN 0-596-00297-1)
when I checked. Someone please let us know what
it has about PPP.
Regards, Peter E.
