Dear Kunia:
you said: I could'nd found any about programming RS232 (COM1/2)
under winXP. Why under Win XP ?...any Windows version is the same ? No, they're not the same. Things that worked well under Win9x/ME often do not work well under Windows NT/2000/XP/2003 due to notable differences in operating system design. That's not saying it isn't possible to write code that can be used on both, but attention to detail and testing would be required at a minimum. You could try with some Visual Basic help..like MSDN Library for Visual Studio version 6.0 or above. You'll found exactly what you want there.
Search for MSCOMM controll. Same for Visual C++ 6.0...you have examples at MSDN Library too. As I recall, MSComm seems to impose some synthetic limitations which might be problematic for an embedded system designer (i.e., inability to manipulate DTR in an arbitary fashion, inability to access COM ports above 16, etc.) Also, I believe it is not included with newer versions of Visual Studio (although alternatives are available). All of this is not to say the MSComm control is unusable, but that careful evaluation is required to determine if it meets your requirements. You could try this link too !!
