     ufoma — USB mobile phone support


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

           device usb
           device ucom
           device ufoma

     Alternatively, to load the driver as a module at boot time, place the following line in



     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).


     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:

             The modes which are supported by the interface.

             Current mode of the interface.

             Mode to transit when the device is open next.
     The modes are as follows:

     modem   Accepts AT commands and go and pass packet communication data.

             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.

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

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


     Devices supported by the ufoma driver include:

        SHARP FOMA SH902i
        KYOCERA PHS AH-K3001V (a.k.a Kyopon)
        SANYO Vodafone3G V801SA


     Specification can be found at:

     tty(4), ucom(4), umodem(4), usb(4)


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


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