-<p class="Pp">The <code class="Nm">u3g</code> driver provides support for
- USB-to-serial interfaces exposed by many 3G and 4G modems. The supported
- adapters provide the necessary modem port for <a class="Xr">ppp(8)</a>, or
- <span class="Pa">net/mpd5</span> connections. Depending on the specific
- device, extra ports provide other functions such as an additional command
- port, diagnostic port, GPS receiver port, or SIM toolkit port.</p>
-<p class="Pp">The device is accessed through the <a class="Xr">ucom(4)</a>
- driver which makes it behave like a <a class="Xr">tty(4)</a>.</p>
-<p class="Pp">In some adapters a mass storage device supported by the
- <a class="Xr">umass(4)</a> driver is present which contains Windows and Mac
- OS X drivers. The device starts up in disk mode (TruInstall, ZeroCD, etc.)
- and requires additional commands to switch it to modem mode. If your device
- is not switching automatically, please try to add quirks. See
- <a class="Xr">usbconfig(8)</a> and <a class="Xr">usb_quirk(4)</a>.</p>
