Settings on Serial ports

1. Select a port from Configuration -> Serial ports -> Ports Settings

2. Change the port profile to modem

3. In the Port Profile Settings -> Modem Settings section, Check Incoming Connections.

4. Check Enable PPP connections on this modem.

5. Set configurations on Basic serial settings and Advanced Serial Settings sections according to

your environment.

6. Select authentication method of the serial port on Authentication Settings section. If the port

profile is set to modem, you can only select either None or Local authentication method.

7. Select PPP User from the list if you set authentication method to None.” If you select Local

authentication method, you cannot select PPP user separately. To make correct PPP connection

with Local serial port authentication method, you need to have PPP connection configuration

with the same user name and password as in local system user database set on

Configuration > Users. (See step 4 under Incoming PPP Connections above.)

Note: If you are using local authentication for the serial port or internal modem and using a user

in the local database, you must use the Show Terminal window on your PPP client. When the

terminal window opens, login to the serial port and then close the terminal window. PPP

negotiation will start once you close the terminal window.
