Hi Benoit,
I have muddled my way through the subversion bit, hopefully correctly and
compiled the 2454 version. When opening my application I get the error
message "The program has stopped unexpectedly raising signal #11" with the
CPU at 100%. If I try to open the wrong ttyUSBx, the application flags this
error and behaves correctly, so I would assume that if the ttyUSBx opens OK
then the most recent Gambas2 changes have induced the "signal #11" problem.
Can you please let me know how to debug further and assist you with your
efforts.
Thanks and regards,
Tony..

Thanks Benoit and all for your speedy replies..
I'm using the serial port in a timing application with 3 laser through
beam sensors feeding into the CTS, RI and DSR lines of the serial port. In
this mode I don't pass any data, don't really care about flow control and
am only interested in the raw status change events. Working this way I
haven't noticed gross CPU utilisation after opening the port. The
application also uses the UDPsocket to communicate remotely and what I
have noticed is that if the serial port does not open correctly e.g.
"/dev/tty" wrong and the UDPsocket is open, then there is a large amount
of CPU used. Both open correctly and CPU normal.
Can you tell me the polling frequency in Gambas2 2.8 ?
I would assume that there ore other users of Gambas2 who are using the
serial port as a convenient way of passing external events to the
application, so maybe some input from them would also be in order. As
long as there is a mechanism to replicate the Gambas2 2.8 functionality
that I currently use, I'll leave the implementation up to those who know a
lot more than myself. If going back to polling, a property to define the
frequency would be nice.
Thanks again,
Tony.
Can you try the revision #2454? I think I have found and fix another possible
bug, and I'd like to be sure I didn't break anything.
Regards,
