     uhso -- Option N.V. Wireless WAN modem driver

     uhso*     at uhub? port ?

     The uhso driver supports at least the following adapters:

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

     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.

     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.

     The rewrite and this manual page by Iain Hibbert.
