Using the Packet mode in pseudo terminal

[Vanitha Ramaswami <vanitha@xxxxxxxxxxxxxxxx>]

Hi All,

I have created a pseudo terminal. I am running a application
on the slave side of the terminal and reading the data from the
application on the master side. I am using "read" system call
to read the data from the master pty.

Is there a way to separate the packets read from the master
pty. Since i am using read system call, the data is read as
a stream of bytes. I am not able to demarcate the packets
posted by the application.

I saw an option TIOCPKT for pty..? If i just set this ioctl,
how do i separate the packet ? When can i use this
option ?. Can anyone give any example using this option.

Thanks,
Vanitha
