The .Nm driver behaves like a .Xr tty 4 : this means that normal programs such as .Xr cu 1 or .Xr pppd 8 can be used to access the device.

p The .Va portno locator can be used to decide which port to use for devices that have multiple external ports. .Sh FILES l -tag -width "/dev/ttyU?XX" -compact t Pa /dev/ttyU? tty devices t Pa /dev/cuaU? call out devices (see .Xr tty 4 ) .El .Sh SEE ALSO .Xr intro 4 , .Xr tty 4 , .Xr usb 4 .Sh HISTORY The .Nm driver appeared in .Nx 1.5 . .Ox support was added in .Ox 2.7 .
