uhso -- Option N.V. Wireless WAN modem driver
uhso* at uhub? port ?
The uhso driver supports at least the following adapters:
GlobeSurfer iCON 7.2
GlobeTrotter Express 40x
GlobeTrotter Express 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
Diagnostic 2 2
Application 2 4
GPS Control 6
PC Smartcard 7
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.
