NAME
      ports - five-line asynchronous communications interface STREAMS driver

DESCRIPTION
      ports is a STREAMS-based driver that supports a five-line asynchronous
      interface.  Each device supports four RS232 lines and one parallel
      Centronics interface.

      When used in conjunction with the STREAMS line discipline module, ldterm,
      behavior on all lines is as described in termio(7).

FILES

      /dev/lp?          parallel interface
