I have a PC running openSUSE 12.2 x86_64. This PC has a serial port which is connected to an UPS. All is OK. I have inserted an USB to serial converter for a Windows program (Freeze Framer) running with crossover. When I launch this program, it functions correctly but the connexion between the PC serial port and the UPS is broken.
I have made the following tests:

I have created a symbolic link with my program in crossover:
Please when copying/pasting from a terminal window into a post here, make your mouse sweep a little bit larger so that you copy not only the output, but also the prompt, the command and the prompt that follows. And then copy it between CODE tags, not QUOTE tags. That is using the # button from the toolbar.

Because probably it steals the connection that the UPS uses. Nice Windows…

hmmmm…good thought…i remember in the old days (with Windows) you had
to really pay attention to the IRQs or if (for example) you clicked the
mouse the modem would disconnect, i don’t have any idea how, but if you
could FORCE Wine/Freeze Framer to NOT use IRQ 4 (but, i have no idea
which IRQ might be free)…
or, sorry i don’t remember … i think you have to find a Linux AND
Windows guru (i’m neither)…
I think Carlos may be right - crossover perhaps discovers the serial ports, and generates the links that provide access to the serial ports (/dev/ttyS*), and this gets discovered and stolen by your windoze app.
I’m more familiar with wine, and for that one must explicitly supply the required serial port links, eg
ln -s /dev/ttyS0 ~/.wine/dosdevices/com1
so that the only serial port visibility would be the one you supplied for your usb-serial device. I wonder if it would be worth testing the behaviour of your app under wine, assuming it is possible of course…

I don’t think a normal app can steal an IRQ in Linux, that must be done
by wine/crossover with root powers.

Add wine to the mixture…

Yep.

Yes, I think that’s the place to look at first.

Thank you all.
I have tried different com ports, 3 to 8, and changing the link between comx and ttyUSB0. But there were no change.
I also have tried wine, the behaviour is the same.
I have also tried on another PC running openSUSE 11.3. but i have not use the PC serial port, but two USB to serial converters, and the problem did no appear.
Strange, is not it?
