LCP: timeout sending Config-Requests
Connection terminated. 

Don't know why the target is ignoring the ConfAck of pppd and why pppd keeps 
with the Confreq...
I have tried also with
pd /dev/ttyUSB0 38400 lock nodetach debug :192.168.254.161 nocrtscts
proxyarp 

$pppd /dev/ttyUSB0 38400 lock nodetach debug :192.168.254.161 crtscts
proxyarp 

and
$pppd /dev/ttyUSB0 38400 lock nodetach debug :192.168.254.161 nocrtscts
proxyarp auth login 

with one, both, none, ip's 


I need some directions on what to do next
I have set the asyncmap on 0xffffffff and 0x00a00000 as some other threads 
said. 


Thnx all.
