Sample: Communications API Function Demonstration Summary: The COMM sample application is designed to demonstrate the basics of using the Win32 communications API functions while maintaining a common code base with Win16 code. More Information: The COMM program performs communications using the Windows functions OpenFile, ReadFile, SetCommState, SetCommMask, WaitCommEvent, WriteFile and CloseFile. This sample creates a background thread to watch for COMM receiver events and posts a notification message to the main terminal window. Foreground character processing is written to the communications port. Simple TTY character translation is performed and a screen buffer is implemented for use as the I/O window. Overlapped file I/O techniques are demonstrated. How To Use: The baud rate, data bits, stop bits, parity, port, RTS/CTS handshaking, DTR/DSR handshaking, and XON/XOFF handshaking can be changed under the Settings menu item. Once the communications settings are setup, the Action menu item can be selected to connect or disconnect the TTY program.Download Driver Pack
