Hi List, i run pppd 2.4.2 in an embedded environment since years. Now i have seen a problem that i never encountered before. Two modem got stuck while handshake. below you can see the logs i have (actualy that is a factual endless loop, what means you see only a few bytes from several megs.) i would like to prevent this from happening again. any with an idea out there ? (it does not seem to be reproducible. after reset the device behaves normal.) re wh Oct 20 13:56:09 pppd[5792]: sent [LCP EchoReq id=0x0 magic=0xd71a0c90] Oct 20 13:56:09 pppd[5792]: sent [IPCP
