Module Name:

    Main.c (this file is the same for both drivers (98DDK & XPDDK))

Abstract:

    Console test app for TiglUsb.sys driver. This program can be considered as an
	example for direct talking with the driver.
	Depending on the NONBLOCKING constant, normal (blocking) or overlapped (non-blocking)
	I/O operations are performed.
	
	This program shows how to open, read, write, close, flush and configure the driver.

Environment:

    user mode only
