HPCRACK
Version 1.0 · Jan Brands
Description
HPCRACK is a password recovery utility for HP 200LX files. It will find the password for Database, Note, Phonebook, Appointment and World Time files. This program was written to show that the file password protection offered by the 200LX is not sufficient to protect highly sensitive data. The C source code is included so that interested parties might learn more about the file protection algorithm and possibly write something that will improve it. This utility is not meant to be used for malicious purposes. Use it at your own risk and please send comments to the author. Freeware.

Send to my palmtop
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.
