Grammatica is a C# and Java parser generator (compiler compiler). It improves upon simlar tools (like yacc and ANTLR) by creating well-commented and readable source code, by having automatic error recovery and detailed error messages, and by support for testing and debugging grammars without generating source code. It supports LL(k) grammars with an unlimited number of look-ahead tokens.
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.
