Actually there's a discussion on it a while back.

This is very interesting. I had the exact same problem a while back using Qextserialport.

Are you working off the SD card, as I found that, once that locked up, to 100% CPU usage, it was if the world stopped.

Hi,

I have a strange problem using 7390 serial ttts5. Sometimes it looses some chars.

The problem usually happens when the processor is working over 95%, and memory is over 85MB (90 available), so I think the problem is related to it.

My program has 2 threads (first for gui and second to execute the "underground" work).
This underground thread sends and reads information to and from serial ports.
I use ttts5 connected to a PID controller and ttyAM0 connected to a GPS.
With this configuration, I can't receive correct status messages from controller (but can send). If i change the ports (ttts5 to GPS), GPS messages don't arrive fine (I don't send messages to GPS).

This port swap makes me think the problem isn't related to my program (same port, different codes).
I have tried my own serial lib, seriallib-0.6 from sourceforge and QextSerialPort from Qt.

Any Ideas?

Adriano
