I have used a device with the Silabs cp2102 chip and using a Prolific chip (used by several brands of usb->serial cables). I have determined that the call to poll() is the source of the problem. Probably because the poll is broken in Mac OS as confirmed here by an Apple employee: http://curl.haxx.se/mail/lib-2005-05/0122.html On the page http://developer.apple.com/technotes/tn2002/tn2071.html Apple suggests using a fake poll() routine based on select(). I have used the fake poll that is linked there to solve the problem. To make it work on Suse Linux (the VM Ware image with Mono 2.0) I have made a change to use sysconf(_SC_OPEN_MAX) instead of OPEN_MAX. I have tested this solution with the cp2102 and Prolific on the mac and with the Prolific chip on linux and confirmed that they behave as expected. I have not tested this on Windows as they seem to use different methods of accessing the serial port. To apply this fix remove the line "#include <sys/poll.h>" from /support/serial.c and insert the line "#include <fakepoll.h>" below the include of errno.h. Then put the fakepoll.h that is attached to this bug in the support directory. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ mono-bugs maillist - mono-bugs@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-bugs
