NAME

ufoma — USB mobile phone support

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

ufoma_load="YES"

DESCRIPTION

The ufoma 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 umodem(4), but the ufoma 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.

The device is accessed through the ucom(4) driver which makes it behave like a tty(4).

SYSCTLS

These devices often have a few interface sets and these interfaces have their role, sometimes multiplexed. These roles are identified with the following sysctl MIBs:

dev.ucom.%d.supportmode

The modes which are supported by the interface.

dev.ucom.%d.currentmode

Current mode of the interface.

dev.ucom.%d.openmode

Mode to transit when the device is open next.

modem

Accepts AT commands and go and pass packet communication data.

handsfree

Accepts AT commands but it does not pass data.

obex

Accepts OBEX frame which is used to exchange telephone book, etc.

vendor1, vendor2

Vendor specific data may be passed.

deactivated

When an interface is recognized by the system but not used, the interface will be set to this mode.

unlinked

When an interface is not yet negotiated, the interface is in this mode.

HARDWARE

Devices supported by the ufoma driver include:

• SHARP FOMA SH902i
• KYOCERA PHS AH-K3001V (a.k.a Kyopon)

HISTORY

The ufoma driver appeared in FreeBSD 7.0, partly derived from the umodem(4) code.

BUGS

Interfaces with multiplexed commands and data and interfaces with commands only are supported.
