6.4.1. Overview

On the VFX/40ESCplus, fonts for ASCII to fax conversion are installed using the ASCII Font Loader or the fax library function fx_loadfont( ).

The ASCII Font Loader enables you to change fonts on hardware channels on a board by board basis. Font loading is supported through the fx_loadfont( ) function.

For more information on fx_loadfont( ), see Chapter 9. Fax Library Function Reference.

Files used by the ASCII Font Loader are copied to the following directories based on the default ..\program files\dialogic\ directory:

Directory Path	File Name	Description
fonts subdirectory	default0.fnt	Default loadable font - Normal
	default3.fnt	Default loadable font - Compressed (specifies the font used for the fax page header)
	katakna0.fnt	Katakana loadable font - Normal
	katakna3.fnt	Katakana loadable font - Compressed
	fonttest.txt	File to produce table of currently loaded ASCII character set (see NOTE below).
samples subdirectory	loadfont.exe	Utility program.
	loadfont.c	ASCII Font Loader library source file.

To determine the fonts currently loaded on a VFX/40ESCplus board, use the SCFAXDEM fax demo program to send the fonttest.txt file to a fax machine. The fonts currently loaded on the specified board will print. The SCFAXDEM demo program is installed by default in the samples subdirectory.

6.4.2. ASCII Font Loader Flow of Control

The flow of control for the ASCII Font Loader is as follows:

1. The ASCII Font Loader opens the first channel on the VFX/40ESCplus board to load the specified font.
2. The ASCII Font Loader utility calls fx_loadfont( ).
3. When fx_loadfont( ) completes, the function returns control to the application.
