DESCRIPTION
     The ucom driver attaches to USB modems, serial ports, and other devices
     that need to look like a tty.  The ucom driver behaves 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 locator can be used to decide which port to use for devices
     that have multiple external ports.

FILES
     /dev/ttyU?    tty devices
     /dev/cuaU?    call out devices (see tty(4))

SEE ALSO
     intro(4), tty(4), usb(4)

HISTORY
     The ucom driver appeared in NetBSD 1.5.  OpenBSD support was added in
     OpenBSD 2.7.

OpenBSD 4.7                    November 7, 2009                              1
