• added several new methods:
  • Opening/closing device
    • open
  • Direct read/write to device
    • dread
    • dwrite
  • I/O Control
    • channels
    • setduplex
    • setfmt
    • speed
• The following methods are now deprecated:
  • getformat
  • queryformat
  • setchannels
  • setdevice
  • setformat
  • setrate
• The following sample-format constants are now exported on use:
  • AFMT_MU_LAW
  • AFMTALAW
  • AFMT_IMA_ADPCM
  • AFMT_U8
  • AFMT_S16_LE
  • AFMT_S16_BE
  • AFMT_S8
  • AFMT_U16_LE
  • AFMT_U16_BE
  • AFMT_MPEG

        Consequently, the 'format' parameter in the init() method should be
        passed in constant rather than string form (string form is deprecated).
        On a similar note, the open flag should be passed as a Fcntl.pm
        constant rather than a string (also deprecated).
