Hi,
I’ve been working on some serial port controller code and keep getting it
locked up. I know that Dev.ser (Dev32.ser actually) handles it OK. The
issue is that I want to handle the interrupts from the serial port in a
special way, take advantage of some special features of my UART, and
Dev32.ser doesn’t seem to be taking advantage of them. So, in my attempt to
make it all work, I am a little stuck. That’s where I thought I saw that
Dev.ser source was available somewhere. If it is, anybody know where I
might download/obtain a copy? I don’t want to use any of the source, just
see how certain cases are handled (Framing Errors, etc) if at all, or if the
interrupts are turned off in other cases as well.
TIA!

Assuming you have an account at quics.qnx.com, you will
find the source in:
/usr/free/qnx4/os/samples/Dev_drivers/Dev.ser.tgz
There may be a way to get this through the web interface also.

Thanks! That’s exactly what I was looking for. Especially one comment in
one of the source files about certain commands overriding other interrupts
(I was having this problem and it was locking up my code, now I know how to
avoid it. I couldn’t find this problem documented ANYWHERE, but now I can
fix it).
TX again!
