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 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 interfaces which are
mapped by function to a standard port number in each driver instance. The defined channels

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 perfor-
intro(4), netintro(4), tty(4), uhub(4), usb(4), ifconfig(8)
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.
