NAME
     ucom - USB tty support

SYNOPSIS
     ucom* at ubsa? portno ?
     ucom* at uftdi? portno ?
     ucom* at umct? portno ?

     ucom* at uplcom? portno ?

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 behaviour 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?
