BOARD 5102S board.

1.3 The CHAPI CHARON utilities

1.3.1 The CHARON CHAPI device creation wizard

The CHAPI device creation wizard is designed to simplify the creation of a CHAPI device:

it is a sequence of GUI dialogs that leads the designer to a Visual Studio C++ project. The

following features are supported:

Project type selection (General CHAPI device, Serial I/O multiplexer / Port, Disk

controller / container, Tape controller / Container, CHAPI Bus / Bus adapter, PCI

replacement hardware based controller / adapter, etc…)

Selection of the required parameters using GUI dialogs related to the selected

project type;

Generation of Visual Studio C++ project files and parameters for the component

under design. The generated project is buildable and satisfies the requirements for

selected type of CHAPI device and the CHAPI support libraries;

1.3.2 HOSTprint

This utility prints data supplied by the emulated printer ports (CHAPI LPV11) of PDP-

11/VAX systems using specified host system printer through a TCP/IP socket (see

example of device which uses HOSTprint).

1.4 CHARON-PDP and CHARON-VAX with CHAPI support.

In CHARON the interface (CHAPI) to peripheral components behaves as a software

replica of the QBUS bus.

The CHAPI standard facilitates the design, modification and exchange of emulated

peripheral devices without requiring a change in the emulator kernel. This opens the way

for third parties to adapt the emulator to specific needs, for instance to add the emulation

of a custom peripheral by building a software replica of the original module.

CHARON emulators with CHAPI is both a production emulator and a test and

development environment for functionality extensions. It includes a design environment,

which supports the replacement, modification, design and test of new components. Most

library functions in the design environment are provided in both a debug and a release

version, and templates for specific device types support rapid development. The CHAPI

can access the CHARON/VAX or CHARON-PDP license key and use its encryption

capabilities for licensing such external components.
