DESCRIPTION
Theucom 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.

adjusted accordingly.
