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

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