ucom(4) [centos man page]

UCOM(4)                                                    BSD Kernel Interfaces Manual                                                    UCOM(4)

ucom -- USB tty support SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file: device ucom Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): ucom_load="YES" DESCRIPTION
The ucom driver attaches to USB modems, serial ports, and other devices that need to look like a tty. The ucom driver shows a behavior like a tty(4). This means that normal programs such as tip(1) or pppd(8) can be used to access the device. The portno locater can be used to decide which port to use for devices that have multiple external ports. BUGS
Prior to FreeBSD 6.0 ucom created /dev/ucom? rather than the uniform device names created today. Old scripts must be adjusted accordingly. FILES

ufoma -- USB mobile phone support SYNOPSIS
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 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 Implementa- tion 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. The modes are as follows: 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: o SHARP FOMA SH902i o KYOCERA PHS AH-K3001V (a.k.a Kyopon) o SANYO Vodafone3G V801SA SEE ALSO
Specification can be found at: tty(4), ucom(4), umodem(4), usb(4) 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. BSD
