To support older HLLAPI applications on 32-bit systems, BlueZone also supports DOS HLLAPI and 16-bit HLLAPI conversations
with 32-bit BlueZone.
Advantages
HLLAPI is a standard API supported by many software vendors.
Disadvantages
|
• |
The specification can be interpreted differently from vendor to vendor causing some incompatibilities. |
|
• |
HLLAPI requires a programmer to write the application. |
|
• |
The interface must be constantly polled by the HLLAPI application to get the status of the host screen. |
|
• |
For new development, the BlueZone Host Automation Object is much easier to implement, and supports a wider range of development
tools.

Note
If you intend on writing a program to interface with BlueZone via the HLLAPI interface, the following documents are provided
on the BlueZone CD-ROM or the BlueZone image.
These documents are located in the
DOCS\WHLLAPI folder on the BlueZone CD-ROM or BlueZone image file.
