DESCRIPTION
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 are:
Channel Name |
Port |
Control |
0 |
Diagnostic |
1 |
Diagnostic 2 |
2 |
Application |
3 |
Application 2 |
4 |
GPS |
5 |
GPS Control |
6 |
PC Smartcard |
7 |

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.

HISTORY
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.
