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

NAME
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 ppp(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. FILES
/dev/cuaU? /dev/ttyU? SEE ALSO
tty(4), uark(4), uchcom(4), uftdi(4), umcs(4), umct(4), umodem(4), umoscom(4), uplcom(4), usb(4), uslcom(4), uvisor(4), uvscom(4) HISTORY
The ucom driver was adopted from NetBSD in March of 2002. This manual page was adopted from NetBSD by Tom Rhodes <trhodes@FreeBSD.org> in April 2002. BUGS
Prior to FreeBSD 6.0 ucom created /dev/ucom? rather than the uniform device names created today. Old scripts must be adjusted accordingly. BSD

U3G(4)							   BSD Kernel Interfaces Manual 						    U3G(4)

NAME
u3g -- USB support for 3G datacards SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device u3g device ucom Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): u3g_load="YES" DESCRIPTION
The u3g driver provides support for the multiple USB-to-serial interfaces exposed by many 3G USB/PCCard modems. The device is accessed through the ucom(4) driver which makes it behave like a tty(4). HARDWARE
The u3g driver supports the following adapters: o Option GT 3G Fusion, GT Fusion Quad, etc. (only 3G part, not WLAN) o Option GT 3G, GT 3G Quad, etc. o Vodafone Mobile Connect Card 3G o Qualcomm Inc. CDMA MSM o Huawei B190, E180v, E220 ('<Huawei Mobile>') o Novatel U740, MC950D, X950D, etc. o Sierra MC875U, MC8775U, etc. (See /sys/dev/usb/serial/u3g.c for the complete list of supported cards for each vendor mentioned above.) The supported 3G cards provide the necessary modem port for ppp, pppd, or mpd connections as well as extra ports (depending on the specific device) to provide other functions (additional command port, diagnostic port, SIM toolkit port). In some of these devices a mass storage device supported by the umass(4) driver is present which contains Windows and Mac OS X drivers. The device starts up in disk mode (TruInstall, ZeroCD, etc.) and requires additional commands to switch it to modem mode. If your device is not switching automatically, please try to add quirks. See usbconfig(5) and usb_quirk(4). SEE ALSO
tty(4), ucom(4), usb(4), usb_quirk(4), usbconfig(5) HISTORY
The u3g driver appeared in FreeBSD 7.2, is based on the uark(4) driver, and written by Andrea Guzzo <aguzzo@anywi.com> in September 2008. AUTHORS
The u3g driver was written by Andrea Guzzo <aguzzo@anywi.com> and Nick Hibma <n_hibma@freebsd.org>. Hardware for testing was provided by AnyWi Technologies, Leiden, NL. BSD
