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 cu(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.
