NAME¶
uhso —
support for several HSxPA
devices from Option N.V.
SYNOPSIS¶
The module can be loaded at boot time by placing the following line in
loader.conf(5):
DESCRIPTION¶
The
uhso driver provides support for several HSxPA devices
from Option N.V. that are based on their packet interface. Each device has a
set of serial ports and a raw IP packet interface. The serial ports of the
device are accessed through the
ucom(4) driver which makes
them behave like
tty(4) devices. The packet interface is
exposed as a network interface.
Establishing a connection on the packet interface is achieved by using the
proprietary AT commands “
AT_OWANCALL
” and
“
AT_OWANDATA
” on any of the available
serial ports.
The network interface must be configured manually using the data obtain from
these calls.
Each device usually have at least two or more serial ports, their individual
purpose can be identified through
sysctl(8). Ports
identified as “Modem” features a normal modem interface that can
be used with PPP. Ports identified as “Diagnostic” uses a
proprietary binary interface used for firmware upgrades, this port does not
have a AT command interface and can not be used to control the device. Other
ports features an AT command interface that can be used for normal device
control.
HARDWARE¶
The
uhso driver should work with most devices from Option. The
following devices have been verified to work
- Option GlobeSurfer iCON 7.2
(new firmware)
- Option iCON 225
- Option iCON 452
- Option iCON 505
The device features a mass storage device referred to as “Zero-CD”
which contains drivers for Microsoft Windows; this is the default mode for the
device. The
uhso driver automatically switches the device
from “Zero-CD” mode to modem mode. This behavior can be disabled
by setting
hw.usb.uhso.auto_switch to 0 using
sysctl(8)
EXAMPLES¶
Establishing a packet interface connection using the AT command interface
available at one of the serial ports
AT+CGDCONT=1,,"apn.provider"
AT_OWANCALL=1,1,1
OK
_OWANCALL=1,1
AT_OWANDATA=1
_OWANDATA: 1, 10.11.12.13, 0.0.0.0, 10.2.3.4, 10.2.3.5, \
0.0.0.0, 0.0.0.0, 72000
Configuring the interface
ifconfig uhso0 10.11.12.13 up
route add default -interface uhso0
echo "nameserver 10.2.3.4" > /etc/resolv.conf
echo "nameserver 10.2.3.5" >> /etc/resolv.conf
The connection can be terminated with
