Java 如何使用SMSLib发送短信

我正在尝试使用SMSLib和USB GSM调制解调器发送短信。我在Maven项目中执行此操作，在pom.xml中有以下依赖项：

        <dependency>
            <groupId>org.smslib</groupId>
            <artifactId>smslib</artifactId>
            <version>dev-SNAPSHOT</version>
        </dependency>

        <dependency>
            <groupId>org.rxtx</groupId>
            <artifactId>rxtx</artifactId>
            <version>2.1.7</version>
        </dependency>

        <dependency>
            <groupId>commons-net</groupId>
            <artifactId>commons-net</artifactId>
            <version>3.1</version>
        </dependency>

        <dependency>
            <groupId>com.googlecode.jsmpp</groupId>
            <artifactId>jsmpp</artifactId>
            <version>2.1.0</version>
        </dependency>

SMSlib的文档说明我需要定义一个网关，如

XYZ g = new XYZ("my-username", "my-password");

据我所知，我相信这应该是连接的调制解调器。我对此非常陌生，因此我无法真正理解“Modem”构造函数的参数在

Modem gateway = new Modem(gatewayId, address, port, simPin, simPin2, smscNumber,memoryLocations)

或

我如何知道参数gatewayId、address、simPin、simPin2和memroyLocations

目前，我在运行代码时遇到以下错误：

Modem gateway = new Modem(gatewayId, parms)
