UCOM(4)		       FreeBSD 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.
