# DESCRIPTION

The uhmodem driver provides support for the Huawei 3G wireless modems and its variants. This type of device has multiple com ports. And some modems have own storage to contain its device driver (for Windows). The uhmodem driver can handle all of these functions on the device.

When the device attached, it will attach multiple ucom devices. The former one is main com device to use communication with your network provider, and others are sub com devices to monitor the condition of data communication and/or network status. These com devices can be used simultaneously.

The device is accessed through the ucom(4) driver which makes it behave like a tty(4).
