.Sh NAME
.Nm ufoma
.Nd USB mobile phone support
.Sh SYNOPSIS
.Cd "device ufoma"
.Cd "device ucom"
.Sh DESCRIPTION
The
.Nm
driver provides support for USB mobile phone terminals in the subset of
the Mobile Computing Promotion Consortium USB Implementation Guideline,
which is adopted by FOMA, the NTT DoCoMo 3G system, terminal.
These are partly like CDC ACM model based modems, which are supported
by
.Xr umodem 4 ,
but the
.Nm
driver recognizes a specific usb descriptor that describes its role and
interface structure, and it will negotiate its role when the device is open.
They support a regular AT command set and
the commands can either be multiplexed with the data stream
or handled through separate pipes.
In the latter case the AT
commands have to be given on a device separate from the data device.
.Pp
The device is accessed through the
.Xr ucom 4
driver which makes it behave like a
.Xr tty 4 .
.Sh SYSCTLS
This device often have a few interface sets and these interfaces
have its role, sometimes multiplexed.
These roles are identified with the following sysctl MIB's:
.Bl -tag -width indent
.It Va dev.ucom.%d.supportmode
The modes which are supported by the interface.
.It Va dev.ucom.%d.currentmode
Current mode of the interface.
.It Va dev.ucom.%d.openmode
Mode to transit when the device is open next.
.El
The modes are as follows:
.Bl -tag -width indent
.It modem
Accepts AT commands and go and pass packet communication data.
.It handsfree
Accepts AT commands but it does not pass data.
.It obex
Accepts OBEX frame which is used to exchange telephone book, etc.
.It vendor1
.It vendor2
Vendor specific data may passed.
.It deactivated
When a interface is recognized to the system and not used, the interface
will set to this mode.
.It unlinked
When a interface is not yet negotiated, the interface is in this mode.
.El
.Sh HARDWARE
Devices supported by the
.Nm
driver include:
.Pp
.Bl -bullet -compact
.It
SHARP FOMA SH902i
.It
KYOCERA PHS AH-K3001V (a.k.a Kyopon)
.It
SANYO Vodafone3G V801SA
.El

.Xr tty 4 ,
.Xr ucom 4 ,
.Xr umodem 4 ,
.Xr usb 4
.Sh HISTORY
The
.Nm
driver
appeared in
.Fx 7-CURRENT, partly from
.Xr umodem 4
code.
.Sh BUGS
Interfaces with multiplexed commands and data and interfaces with
commands only are supported.
