  10   10  DESCRIPTION
  11   11         pckt is a STREAMS module that may be used with a pseudo terminal to
  12   12         packetize certain messages. The pckt module should be pushed (see
  13      -       I_PUSH on  streamio(7I)) onto the master side of a pseudo terminal.
       13 +       I_PUSH on streamio(7I)) onto the manager side of a pseudo terminal.
  14   14  
  15   15  
  16   16         Packetizing is performed by prefixing a message with an  M_PROTO
  17   17         message.  The original message type is stored in the 1 byte data
  18   18         portion of the M_PROTO message.
  19   19  
  20   20  
  21   21         On the read-side, only the M_PROTO, M_PCPROTO, M_STOP, M_START,
  22   22         M_STOPI, M_STARTI, M_IOCTL, M_DATA, M_FLUSH, and  M_READ messages are
  23   23         packetized. All other message types are passed upstream unmodified.
  24   24  
  25   25  
  26      -       Since all unread state information is held in the master's stream head
       26 +       Since all unread state information is held in the manager's stream head
  27   27         read queue, flushing of this queue is disabled.
  28   28  
  29   29  
  30   30         On the write-side, all messages are sent down unmodified.
  31   31  
  32   32  
  33      -       With this module in place, all reads from the master side of the pseudo
  34      -       terminal should be performed with the  getmsg(2) or getpmsg() function.
  35      -       The control part of the message contains the message type. The data
  36      -       part contains the actual data associated with that message type. The
  37      -       onus is on the application to separate the data into its component
  38      -       parts.
