NAME

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

SYNOPSIS

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

           uhso_load="YES"

DESCRIPTION

     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 interface.

     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.

HARDWARE

     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).

EXAMPLES

     Establishing a packet interface connection using the AT command interface available at one of the serial
     ports

           AT+CGDCONT=1,,"apn.provider"
           AT_OWANCALL=1,1,1
           OK
           _OWANCALL=1,1

           AT_OWANDATA=1
           _OWANDATA: 1, 10.11.12.13, 0.0.0.0, 10.2.3.4, 10.2.3.5, \
                   0.0.0.0, 0.0.0.0, 72000

     Configuring the interface

           ifconfig uhso0 10.11.12.13 up
           route add default -interface uhso0
           echo "nameserver 10.2.3.4" > /etc/resolv.conf
           echo "nameserver 10.2.3.5" >> /etc/resolv.conf

     The connection can be terminated with

           AT_OWANCALL=1,0,1
