Network driver bug - pseudo ttys
Hello,
I am porting a driver for a network card for QNX Neutrino 6.3.2. So far things are going well, but I'm running into a
strange bug which I cannot solve.
The card initializes fine, the interface is brought up and it starts to receive interrupts (nothing is sent/received
yet). After one or two seconds all terminals go down and the card hangs. Opening a new terminal fails with the message
'cannot find a free pseudo tty', but the system still works and I can reboot the system from the menu.
What is going wrong here? I cannot find any code in my driver that directly uses pseudo-ttys, but perhaps that is buried
in some library call?
Help!
Kind regards,
- Theo van Klaveren
