UHSO(4)			 BSD Kernel Interfaces Manual		       UHSO(4)

NAME
     uhso — Option N.V. Wireless WAN modem driver

SYNOPSIS
     uhso*     at uhub? port ?

HARDWARE
     The uhso driver supports at least the following adapters:

	   GlobeSurfer HSUPA
	   GlobeSurfer iCON 7.2
	   GlobeTrotter Express 40x
	   GlobeTrotter Express HSUPA
	   GlobeTrotter HSUPA
	   GlobeTrotter Max HSDPA
	   GlobeTrotter Module 382
	   GlobeTrotter iCON 225
	   GlobeTrotter iCON 321
	   GlobeTrotter iCON 322
	   GlobeTrotter iCON 401
	   GlobeTrotter iCON 505
	   GlobeTrotter iCON EDGE

DESCRIPTION
     The Option N.V. modems appear at first as a umass(4) device containing
     the Windows and MacOS drivers and, upon receipt of a SCSI "REZERO UNIT"
     command, will detach from the USB bus and reattach as a Wireless WAN
     modem.  Unless disabled by clearing the sysctl(8) variable
     hw.uhso.autoswitch, the driver will handle that automatically.

     The modems provide a number of IO channels spread over several USB inter‐
     faces which are mapped by function to a standard port number in each
     driver instance.  The defined channels are:

	   Channel Name	      Port
	   Control	      0
	   Diagnostic	      1
	   Diagnostic 2	      2
	   Application	      3
	   Application 2      4
	   GPS		      5
	   GPS Control	      6
	   PC Smartcard	      7
	   Modem	      8
	   MSD		      9
	   Voice	      10
	   Network	      11

     Apart from the Network port, which is attached as a network interface,
     the ports are attached as tty(4) devices using the port number as the
     minor device number.  In order to connect using pppd(8), the Modem tty
     should be used (eg /dev/ttyHS0.08).

     The Network port provides a direct IPv4 interface, but before this can be
     used the modem needs to be placed in connected mode and network settings
     subsequently retrieved using the proprietary "_OWANCALL" and "_OWANDATA"
     AT commands on the Control port.

     Note that the Modem and Network ports should not be enabled at the same
     time for USB performance reasons.

HISTORY
     This driver originated as the hso module for FreeBSD written by Frederik
     Lindberg.	It was rewritten for NetBSD, and to provide more complete
     device support with information extracted from the hso driver for Linux
     provided by Option N.V.
