Hardware modem - Connection problem

[yannisv]

Hi,

I seem to get my Diamond hardware modem going on the laptop after having connected it to a usb-to-serial adapter since there are no serial ports on the laptop. The connection is established but some time later (usually 5-15 minutes) it seems to disconnect. I have set idle-time to 0 seconds after a recommendation made in an earlier posting on the forum! I have also set it to higher values!Still nothing!
This is the log i get:
SuSE Meta pppd (smpppd-ifcfg), Version 1.59 on linux.

Can someone help? I even tried enabling stupid mode but still nothing! Also i checked the connectors on the adapter to the modem and the USB hub, but all seems ok too!
Thanks in advance!
BYTHEWAY i use Kinternet to dial

It seems as if your modem isn't sending out the packets neccessay to keep the connection alive. Your ISP looks for these pakets and if it doesn't get them in a certain amount of time(in your case 7.5 min) it disconnects you.

The line:

pppd[0]: No response to 4 echo-requests

led me to beleive this is the problem
However i have no idea how to fix this problem

[rpolocz]

I was able to fix this by putting the following 2 lines in my file that is in /etc/ppp/peers

lcp-echo-failure 0
lcp-echo-interval 0
