UHSO(4) Kernel Interfaces Manual UHSO(4) NAME uhso -- Option N.V. Wireless WAN modem driver SYNOPSIS uhso* at uhub? port ? HARDWARE The uhso driver supports at least the following adapters: GlobeSurfer HSUPA GlobeSurfer iCON 7.2 GlobeTrotter Express 40x GlobeTrotter Express HSUPA GlobeTrotter 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 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 Modem 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. FILES /dev/ttyHS?.?? /dev/dtyHS?.?? /dev/ctyHS?.??

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.
