The OnTimeouts event occurs when other application changes the timeouts parameters of the virtual serial port (only Windows NT/2K/XP).

OnTimeouts(

      LONG ReadIntervalTimeout,      

      LONG ReadTotalTimeoutMultiplier,      

      LONG ReadTotalTimeoutConstant,      

      LONG WriteTotalTimeoutMultiplier,      

      LONG WriteTotalTimeoutConstant      

);

 

Parameters:

  • ReadIntervalTimeout [out] : Maximum time, in milliseconds, allowed to elapse between the arrival of two characters on the communications line.
  • ReadTotalTimeoutMultiplier [out] : Multiplier, in milliseconds, used to calculate the total time-out period for read operations. For each read operation, this value is multiplied by the requested number of bytes to be read.
  • ReadTotalTimeoutConstant [out] : Constant, in milliseconds, used to calculate the total time-out period for read operations. For each read operation, this value is added to the product of the ReadTotalTimeoutMultiplier member and the requested number of bytes.
  • WriteTotalTimeoutMultiplier [out] : Multiplier, in milliseconds, used to calculate the total time-out period for write operations. For each write operation, this value is multiplied by the number of bytes to be written.
  • WriteTotalTimeoutConstant [out] : Constant, in milliseconds, used to calculate the total time-out period for write operations. For each write operation, this value is added to the product of the WriteTotalTimeoutMultiplier member and the number of bytes to be written.
