     uhso — support for several HSxPA devices from Option N.V.


     The module can be loaded at boot time by placing the following line in loader.conf(5):



     The uhso driver provides support for several HSxPA devices from Option N.V. that are based
     on their packet interface.  Each device has a set of serial ports and a raw IP packet
     interface.  The serial ports of the device are accessed through the ucom(4) driver which
     makes them behave like tty(4) devices.  The packet interface is exposed as a network

     Establishing a connection on the packet interface is achieved by using the proprietary AT
     commands “AT_OWANCALL” and “AT_OWANDATA” on any of the available serial ports.

     The network interface must be configured manually using the data obtain from these calls.

     Each device usually have at least two or more serial ports, their individual purpose can be
     identified through sysctl(8).  Ports identified as “Modem” features a normal modem interface
     that can be used with PPP.  Ports identified as “Diagnostic” uses a proprietary binary
     interface used for firmware upgrades, this port does not have a AT command interface and can
     not be used to control the device.  Other ports features an AT command interface that can be
     used for normal device control.


     The uhso driver should work with most devices from Option.  The following devices have been
     verified to work

        Option GlobeSurfer iCON 7.2 (new firmware)
        Option GlobeTrotter Max 7.2 (new firmware)
        Option iCON 225
        Option iCON 452
        Option iCON 505

     The device features a mass storage device referred to as “Zero-CD” which contains drivers
     for Microsoft Windows; this is the default mode for the device.  The uhso driver
     automatically switches the device from “Zero-CD” mode to modem mode.  This behavior can be
     disabled by setting hw.usb.uhso.auto_switch to 0 using sysctl(8).

     of the serial ports

     Configuring the interface

           ifconfig uhso0 up
           route add default -interface uhso0
           echo "nameserver" > /etc/resolv.conf
           echo "nameserver" >> /etc/resolv.conf

     The connection can be terminated with



     uhsoctl(1), ucom(4), usb(4)
