  DESCRIPTION
         pckt is a STREAMS module that may be used with a pseudo terminal to
         packetize certain messages. The pckt module should be pushed (see
!        I_PUSH on  streamio(7I)) onto the master side of a pseudo terminal.
  
  
         Packetizing is performed by prefixing a message with an  M_PROTO
         message.  The original message type is stored in the 1 byte data
         portion of the M_PROTO message.

  DESCRIPTION
         pckt is a STREAMS module that may be used with a pseudo terminal to
         packetize certain messages. The pckt module should be pushed (see
!        I_PUSH on streamio(7I)) onto the manager side of a pseudo terminal.
  
  
         Packetizing is performed by prefixing a message with an  M_PROTO
         message.  The original message type is stored in the 1 byte data
         portion of the M_PROTO message.
*** 21,46 ****
         On the read-side, only the M_PROTO, M_PCPROTO, M_STOP, M_START,
         M_STOPI, M_STARTI, M_IOCTL, M_DATA, M_FLUSH, and  M_READ messages are
         packetized. All other message types are passed upstream unmodified.
  
  
!        Since all unread state information is held in the master's stream head
         read queue, flushing of this queue is disabled.
  
  
         On the write-side, all messages are sent down unmodified.
  
  
!        With this module in place, all reads from the master side of the pseudo
!        terminal should be performed with the  getmsg(2) or getpmsg() function.
!        The control part of the message contains the message type. The data
!        part contains the actual data associated with that message type. The
!        onus is on the application to separate the data into its component
!        parts.
