- Communications Demonstration
-
-
- SUMMARY
- =======
-
- The COMM sample (TTY) is designed to demonstrate using the Win32
- communications functions while maintaining a common code base with
- 16-bit Windows code.
-
- MORE INFORMATION
- ================
-
- The program performs communications using the functions OpenFile, ReadFile,
- SetCommState, SetCommMask, WaitCommEvent, WriteFile, and CloseFile.
-
- The program 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.
-
- Usage:
-
- 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 set, the Action menu item can be
- selected to connect or disconnect the program.
