HP 15c Collector's Edition save/restore does not work

[fossy]

Hello

Could anybody get this to work?

I have a HP 15c_CE with new firmware (HP_IAR_USB 120ms.bin - checksum 0A0Ah - 2024-06-03) and the VoyagerSave.exe from https://hpcalcs.com/download.

As mentioned in https://hpcalcs.com/downloads/apps/Voyag...ctions.pdf the calculator should go into HID mode after pressing [ON]/[f]&[ENTER] - and leave it with a hit on [ON].

Even this is not true for me. The calculator keeps only in the HID mode while I keep holding [f]&[ENTER]. When I release [f]&[ENTER] the calculator is switched on in normal operation and HID mode is off.

I cannot imagine that the holding from [f]&[ENTER] is the "plan" to save and restore calculators memory.

When I hold the calculator in HID mode with my left hand and key in with my right hand on the PC

Code:

VoyagerSave.exe -s memory

I get a file memory with exactly 0 Bytes. Even this does not work.

Does this work (and if how) for anybody?
