- 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.
