Introduction
Unpack the software from the CD-ROM in accordance with the instructions provided with the licence.
The Software utilities contain simple DOS routines in both C, QBASIC and Windows DLL / LIB (16bit
only) for use with Visual Basic and Microsoft C++.

Figure 2.0 Typical Project Arrangement.
Figure 2.0 shows a typical C project, Calibre UK Ltd have produced the library files, SPICA.LIB,
MPICA.LIB, CPICA.LIB and LPICA.LIB, which contains all the low level functions required to interface
to the adapter via the parallel port. These libraries cover the standard memory models, the library
appropriate to the memory model of your project will require linking with the object files.
