IA260-261-262 EM-2260 LX User’s Manual  Managing Communications 
Setting up a Machine for Incoming PPP Connections 
This first example applies to using a modem, and requiring authorization with a username and 
password. 
pppd/dev/ttyM0 115200 crtscts modem 192.168.16.1:192.168.16.2 login auth 
You should also add the following line to the file /etc/ppp/pap-secrets: 
* * ““ * 
The first star (*) lets everyone login. The second star (*) lets every host connect. The pair of 
double quotation marks (““) is to use the file /etc/passwd to check the password. The last star (*) 
is to let any IP connect. 
The following example does not check the username and password: 
pppd/dev/ttyM0 115200 crtscts modem 192.168.16.1:192.168.16.2
