35 .Nd USB mobile phone support
42 driver provides support for USB mobile phone terminals in the subset of
43 the Mobile Computing Promotion Consortium USB Implementation Guideline,
44 which is adopted by FOMA, the NTT DoCoMo 3G system, terminal.
45 These are partly like CDC ACM model based modems, which are supported
50 driver recognizes a specific USB descriptor that describes its role and
51 interface structure, and it will negotiate its role when the device is open.
52 They support a regular AT command set and
53 the commands can either be multiplexed with the data stream
54 or handled through separate pipes.
55 In the latter case the AT
56 commands have to be given on a device separate from the data device.
58 The device is accessed through the
60 driver which makes it behave like a
63 These devices often have a few interface sets and these interfaces
64 have their role, sometimes multiplexed.
65 These roles are identified with the following sysctl MIBs:
66 .Bl -tag -width indent
67 .It Va dev.ucom.%d.supportmode
68 The modes which are supported by the interface.
69 .It Va dev.ucom.%d.currentmode
70 Current mode of the interface.
71 .It Va dev.ucom.%d.openmode
72 Mode to transit when the device is open next.
74 The modes are as follows:
75 .Bl -tag -width indent
77 Accepts AT commands and go and pass packet communication data.
79 Accepts AT commands but it does not pass data.
81 Accepts OBEX frame which is used to exchange telephone book, etc.
82 .It Li vendor1 , vendor2
83 Vendor specific data may be passed.
85 When an interface is recognized by the system but not used, the interface
86 will be set to this mode.
88 When an interface is not yet negotiated, the interface is in this mode.
