Hi All,
I have been trying for several weeks to transfer our product to linux using wine. I am so close it hurts! The only issue has been the serial ports. Threads, sockets, and timers appear to be working as advertised (an impressive feat of wine as it is!). However the serial port has failed me. I have used versions 20040716 and 20040505 both as RPM's and source code (with various patches applied to the source). The major issue is reliability. I can successfully get test programs to echo back a character received on the serial port. However when I use the port in anger it often drops bytes. Calls to ReadFile will drop the last byte when the packet size is 30 bytes, and up to the last 5 bytes when the packet size is 200+ bytes. After a while calls to WriteFile will actually stop sending bytes even though it returns successfully. The program has several threads but I have modified it so that the calls to ReadFile/Writfile are in the same thread inside a loop. I set the timeout parameters to return immediately from a ReadFile with any available bytes. If you are interested I can post the shell of my code.
Yes, would be a good idea. The best way would be to create a demo program that's as small as possible exhibiting the problem. Then file it with a bug report. But maybe something like WINEDEBUG=+file,+win32,+comm,+server,+relay and a modified Wine with additional traces in the comm area could help? Doesn't sound like it's extremely difficult to spot, but then I didn't debug the program...
