NAME

     uhmodem -- USB support for Huawei 3G wireless modem device


SYNOPSIS

     uhmodem*  at uhub?
     ucom*  at uhmodem?


HARDWARE

     The uhmodem driver supports the following adapters:

           Huawei E220

           E-mobile D02HW

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 for-
     mer one is main com device to use communication with your network
     provider, and others are sub com device 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).
