Intermec 5020 User Manual - Transmitting On A Full Field

Scan-ahead and type-ahead are always available. While the device is waiting 

for a new screen, all scanned and keyed data is buffered. When the device 

receives a new screen with input fields, it applies the buffered data to the 

new screen. If an auto-transmit field is filled in before the end of the screen 

is reached, the screen is transmitted, and the remainder of the scan-ahead or 

type-ahead data waits for the next screen. 

If the device receives a new screen that has no input fields, the device 

assumes that the screen is an error message. All scan-ahead data and type-

ahead data are discarded. 

Type-ahead can include the arrow keys and any of the alphanumeric keys, 

but it cannot include action keys such as a function key or the Enter key. 

You can disable scan-ahead by:

• using type-ahead.

or

• changing IMDCB.INI on the device so that SCANAHEAD equals 0.

Transmitting on a Full Field

The following procedure explains how to transmit the content of a full field 

without pressing Enter. For example, in a field with a Yes or No question, 

the data is transmitted when you press Y or N.

To transmit on a full field

1

Copy from your device. For help, see the user’s manual for your device.

2

In IMDCB.INI, add TRANSMIT_ON_FULL.

3

Save the changes to IMDCB.INI. Do not change the name of the .ini 

file.

4

Load IMDCB.INI on your device. For help, see the user’s manual for 

your device.

5

In your HTML application, add TRANSMIT to the field tag that you 

want to have transmit when full.

6

Load and run your application.

Note: Screens with input fields have no way to ensure that the scan-ahead 

data or type-ahead data is put in the correct field. The receiving application 

must validate the data.
