I found and fixed a problem in drvAsynSerialPortWin32.c.  When pasynUser->timeout was 0 for a read operation, and the number of characters available to read was 0, it was returning asynSuccess.  This is incorrect, it should return asynTimeout.  Dirk also found a problem that when pasynUser->timeout was 0 it was not returning immediately.

 

With these fixes StreamDevice works correctly with local serial ports on WIN32.

 

These fixes will be in the next release of asyn, R4-23.

Folks,

 

I am trying to use StreamDevice with a local serial port on win32-x86.  It is not working.  I’d like to know if the problem is specific to my setup.

 

Has anyone else used StreamDevice with local serial ports on win32-x86 or windows-x64?

 

Thanks,

Mark
