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.
