The top line of this screen identifies the area selected in the Area Selection screen. Once
a character has been received, IPL stays in this screen until an entire image has been
received, or until an error is detected. The only other way to exit from this screen is to reset
the terminal by holding the power switch down for 16 seconds. As more data is received,
the Receiving Screen is updated to reflect the current status. The first record in the image
identifies the area to be processed. When IPL receives the record, it verifies that the area

The top line of the display identifies the actual area being processed. The remainder of the
display identifies the number of 8Kbyte pages to erase, receive and write. To process the
data, IPL must receive, erase, and write the entire image. With the exception of the disk
images, IPL receives the entire image before starting the erase, and completes the erase
before starting to write. With disk images, IPL multiplexes all three operations as data is
received. Eventually, (assuming no errors), all three counts reduce to 0.
When the entire image is received, and the flash is updated, IPL displays the Verify screen:
This screen continues to display while the image is being verified. Once the image is
verified, IPL displays the Success screen:
