The following Utilities are included in the Dolphin ROM image and are automatically 

loaded when the terminal boots. They are NOT included on the Dolphin OS and 

Development System Disk.

Enhanced Video System (EVS) is a TSR 

that traps standard video BIOS (INT 10H) 

calls, and overlays hardware-specific 

support for the Dolphin’s LCD.  In 

addition, EVS provides application and 

system level Status line support. 

POWERMON.EXE is a TSR that 

monitors battery status and power usage.  

POWERMON.EXE is automatically

Dolphin Application Development 

 

Compiling Applications for the Dolphin 

Dolphin application development is straightforward.  Since Dolphin is DOS-

compatible, most of the application can be tested on a desktop computer. 

Although Dolphin is DOS-compatible, it provides many unique features that are not 

built into most PCs.  For example, it has an integrated bar code scanner.  The Dolphin 

libraries provide an API that allows an application to use these features.  There are four 

libraries provided for linking into applications: 

• 

dolphins.lib for small memory models 

• 

dolphinm.lib for medium memory models 

• 

dolphinc.lib for compact memory models 

• 

dolphinl.lib for large memory models 

The header file, dolphin.h, in the c:\dolphin\devtools\ directory contains useful 

declarations for using these libraries.
