The SetChars method sets the special characters, which are used for handshake flow control.


BOOL SetChars(

      CHAR EofChar,      

      CHAR ErrorChar,      

      CHAR BreakChar,      

      CHAR EventChar,      

      CHAR XOnChar,      

      CHAR XOffChar      

);

 

Parameters:

  • EofChar [out] : Value of the character used to signal the end of data.
  • ErrorChar [out] : Value of the character used to replace bytes received with a parity error.
  • BreakChar [out] : Value of the character used to signal break event.
  • EventChar [out] : Value of the character used to signal an event.
  • XOnChar [out] : Value of the XON character for both transmission and reception.
  • XOffChar [out] : Value of the XOFF character for both transmission and reception.

Return Values : If the function succeeds, the return value is TRUE, otherwise the return value is FALSE.

Notes:

  1. This method is available starting from Windows 2000 only.
  2. These port settings are actual untill they are not changed by VSP AX or application, which opened virtual serial port. If these settings are changed, you get a corresponding message (in that case OnChars event). Be carefull, when you are changing this parameter from VSP AX in event body, as you might get into an endless loop.
