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 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
     /dev/cuaU?

     /dev/ttyU?

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.
