[Gambas-user] Serial Port Change Events Not Working after Upgrade to Karmic
Hi, I have a Gambas2 application (gb.qt) checking for status change events on the CTS, RI and DSR signals (SerialPort-gb.net class) of a USB to serial converter (Prolific pl2303) which works fine on Ubuntu 9.04 (Gambas2 2.8 and kernel 2.6.28-16-generic 32bit). After upgrade to Ubuntu 9.10 (Gambas2 2.13 and kernel 2.6.31-15-generic 32bit) the status changes are no longer working. The serial port opens without error but no status change events are flagged. The problem is also evident in the serial port example on Ubuntu 9.10. I have compiled Gambas2 2.18 onto Ubuntu 9.04 but it still fails so my guess is that somewhere between Gambas2 2.8 and 2.13 this functionality stopped working. Any assistance would be appreciated, thanks.. -- Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.

Tony, Try to compile gambas2 again. I got similar problem with apps after upgrade ubuntu from 9.04 yo 9.10 and it was necessary to do this: sudo apt-get install build-essential autoconf libbz2-dev libfbclient2 libmysqlclient15-dev unixodbc-dev libpq-dev libsqlite0-dev libsqlite3-dev libgtk2.0-dev libldap2-dev libcurl4-gnutls-dev libgtkglext1-dev libpcre3-dev libsdl-sound1.2-dev libsdl-mixer1.2-dev libsdl-image1.2-dev libsage-dev libxml2-dev libxslt1-dev libbonobo2-dev libcos4-dev libomniorb4-dev librsvg2-dev libpoppler-dev libpoppler-glib-dev libasound2-dev libesd0-dev libesd-alsa0 libdirectfb-dev libaa1-dev libxtst-dev libffi-dev kdelibs4-dev firebird2.1-dev libqt4-dev and after I downloaded gambas from source and compile again.

You will get the Read event only, but you won't burn CPU power. - Setting FlowControl to any other value. You will get all events, but you will have to poll.

Re: [Gambas-user] Serial Port Change Events Not Working after Upgrade to Karmic
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. Benoît Minisini wrote: Thanks for the suggestion Ricardo.
