The palmtop must be waiting before you press the button, or the transfer will fail. It is the palmtop that announces it is ready, not the other way round.
Your browser cannot talk to the serial port. Direct sending uses the Web Serial API, which only exists in Chrome, Edge and Opera on desktop — not in Firefox, Safari or any mobile browser.
Download the file with the button above and copy it to the palmtop your usual way.
