The TapiComm sample uses both the Telephony API and the Win32 Communications API to demonstrate one way to implement a very simple TTY application. While the user interface and TTY emulation are very rudimentary, the TAPI and comm modules are fairly complete.
The project demonstrates many Windows common controls, including the extensive use of image lists. The project was used in the book "The Revolutionary Guide To MFC 4 Programming With Visual C++", published by Wrox Press.
