Hi.
I just got myself a USB-GPS (GlobalSat BU-353) and wanted to run SeaClearII, a navigation-program with it. Turns out that Wine got confused when the USB->Serial-driver wasn't acting like a real serial-device though.
The app does what it's supposed to do, but Wine consumes 100% of the available CPU.
After some googling I found a patch that resolved this issue perfectly, and I'm curious why it never made it into trunk.
The patch: http://www.nabble.com/serial-04-04%3A-fix%3A-WaitCommEvent()-does-not-work-a...
I only managed to apply this patch to 1.1.17. Later releases had changed too much for my non-programmer-brain to cope with..
I would really appreciate if someone in the know could check the patch out and if possible apply it to wine-proper..
Thanks in advance.. /Henrik

I posted the patch on wine-patches. But nobody commented on it so I don't know if it is ok or not. As we need it for several applications we use I have a version for newer wine versions. It is attached.
The patch actually fixes 3 things:
1) Fix WaitCommEvent() when used asynchronously
2) make wait_for_event() detect when serial fd is not valid any more
3) make events work better with serial devices not supporting TIOCGICOUNT (Most drivers of usb2serial adapters do not support TIOCGICOUNT, nor do pseudo terminals)
Fix for 3) could be separated from 1) und 2) but I can't test 1) and 2) without 3).

If it's possible, submit one patch for each one thing getting fixed.

Separating 1) und 2) does not make sense.
3) needs fixes 1) and 2).
Separating 3) is possible but I can't test 1) and 2) alone.
