For example, the genericDialUp.conf configuration looks like this (the actual file isencoded in UTF-8):<p> <pre>[Info]Name = Dial-up - PPPType = dialupLayer = TCP/IP[Help]Help = For dial-up connections through a modem and plain telephone line.Help[de] = F黵 W鋒lverbindungen mit Modem und Telefon.[Properties]Auto = 0Device = pppCardType = serial</pre><p> To add a network service that is merely a specific dialup service,you need only provide another configuration files, for example:<p> <pre>[Info]Name = SuperNet ISPType = dialupLayer = TCP/IP[Help]Help = Connect to your local SuperNet(tm) point-of-presence.[Properties]Auto = 0Device = pppCardType = serialpassword = secretphone = 555555555speed = 115200username = customer</pre><p> However, to add a service beyond the scope of the existingservices, you can define your own network service Type,by creating a NetworkInterface plugin.<hr><h2>Member Function Documentation</h2><h3 class=fn>QWidget * <a name="addStateWidget"></a>NetworkInterface::addStateWidget ( QWidget * parent, <a href="config.html">Config</a> & cfg ) const<tt> [virtual]</tt></h3>Returns a widget, with <em>parent</em> as its parent, that showsthe state of the network service defined by <em>cfg</em>.<p> By default, 0 is returned (no state widget).<h3 class=fn>QString <a name="cardType"></a>NetworkInterface::cardType ( <a href="config.html">Config</a> & cfg ) const<tt> [virtual]</tt></h3>Returns the pcmcia card type associated with this service.<p> By default, the Properties.CardType value in <em>cfg</em> is returned.<h3 class=fn>bool <a name="create"></a>NetworkInterface::create ( <a href="config.html">Config</a> & cfg )<tt> [pure virtual]</tt></h3><p> Performs any system state changes required forthe network service defined by <em>cfg</em>.
