.Sh NAME
.Nm hso
.Nd support for several HSxPA devices from Option N.V.
.Sh SYNOPSIS
The module can be loaded at boot time by placing the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
uhso_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
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
.Xr ucom 4
driver which makes them behave like a
.Xr tty 4 .
The packet interface is exposed as a network interface.
.Pp
To establish a connection on the packet interface the use of the proprietary
AT commands
.Dq Li AT_OWANCALL
and
.Dq Li AT_OWANDATA
are required on any of the serial ports.
.Pp
The network interface must be configured manually using the data obtain from
these calls.
.Pp
Each device usually have at least two or more serial ports, their individual purpose
can be identified through
.Xr sysctl 8 .
.Sh HARDWARE
The
.Nm
driver supports at least the following cards
.Pp
.Bl -bullet -compact
.It
Option GlobeSurfer iCON 7.2 (new firmware)
.It
Option iCON 225
.El
.Pp
The device features a mass storage device referred to as
.Dq Zero-CD
which contains drivers for Microsoft Windows.
The driver automatically switches the device to modem mode.
