I observed “tinit” issue in QNX 6.5.0. 

1)	Connect to QNX 6.5.0 box using hypertermial
2)	Login to the box, once the login prompt is displayed
3)	Disconnect the hyperterminal
4)	Connect back the hyperterminal
5)	Shell prompt is displayed instead of the login prompt.

Hyperterminal disconnection is not logging-out the terminal session. However, with QNX 6.3.2 hyperterminal disconnection
 logs out the user.

Why "tinit" is behaving different in both QNX 6.3.2 and 6.5.0, are there any known bugs with tinit in QNX 6.5.0
