uhso

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 interfaces 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.
