DESCRIPTION    [Toc]    [Back]

     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.
