/**
 * Gateway mapped to org.smslib.modem.IPModemGateway. Used for IP connected GSM
 * modems.
 * <p>
 * Configuration Items:<br />
 * <b>ip</b>: the IP address of the modem, for example 192.168.100.110.<br />
 * <b>port</b>: the IP port to which the modem is listening, for example 9900.<br />
 * <b>manufacturer</b>: the manufacturer string, for example Nokia<br />
 * <b>model</b>: the modem string, for example 6310i<br />
 * <b>protocol</b>: the protocol in use, either PDU or TEXT<br />
 * <b>pin</b>: the SIM PIN<br />
 * <b>inbound</b>: "yes" (without quotes) if the gateway should be treaded as
 * an inbound gateway, otherwise "no".<br />
 * <b>outbound</b>: "yes" (without quotes) if the gateway should be treaded as
 * an outbound gateway, otherwise "no".<br />
 * <p>
 * Sample configuration section in <b>SMSSvr.conf</b> for a single IP
 * modem:<br />
 * <br />
 * gateway.0=myModem, IPModem<br />
 * myModem.port=192.168.100.110<br />
