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?

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.
