Intermec 6100 Reference Guide

There are other usable development environments.  Here are some guidelines

that can help to determine whether a particular environment is viable for a 6100

application.

1. How much space is required?

Many environments assume that the target machine is a desktop or laptop

with virtually unlimited hard drive space.  This is certainly not the case

with a handĆheld computer; memory is still at a premium.  For example,

Power Builder is a very popular environment for development.  However,

just to get an application started, Power Builder uses more than three

megabytes of DLLs in addition to Windows just to run the Hello World proĆ

gram.  Power Builder applications tend to be large and slow; at this time, it

is not recommended.

2. (Windows) How are the dialogs being stored?

This is a question you must ask if you want to use a tool that provides one

environment for both DOS and Windows applications.  If the dialog inforĆ

mation is stored as separate files, you will find it very hard to get adequate

response time for drawing the screens.  Also, some of these tools insulate

you from the Windows APIs; consequently, it becomes very difficult to use

any of the APIs that are provided for you.

3. The 6100 Computer uses a 33 MHz 386 processor.  Test the performance of

your application on a comparable computer.

The following steps outline a general approach for equipment setup:

1. Connect power to the single dock.
2. Connect a NULL modem cable between the dock and a serial port on the

desktop or portable PC.

3. If the PC Card slots contain cards, remove the cards.
4. Install the main battery.
5. Insert the 6100 Computer into the dock.
6. As the 6100 Computer starts the boot process, you will hear one of the

following beep signals:

"

one beep:  boot files are moved into shadow RAM from an SRAM card

in drive B: (master mode boot cycle)

"

two beeps:  shadow RAM receives files through a download process

through a communications port.

"

three beeps:  shadow RAM receives files from flash memory.

7. Verify that the 6100 Computer has booted.  It should show a box with

NORAND UTILITIES" at the top.
If this is not the case, then press the reset switch on the 6100 Computer.

The reset switch is located under the top lid, to the left of the PC Cards,

near the front eject button (slot 1).  For a diagram showing the location of

the reset button and PC Card drives, refer to Figure 1Ć1, page 1Ć17.
