Hyperterminal not showing any text

[SuperXX]

Hi,

I´m trying to recover my calculator with USB-TTL but nothing seems to be working. I´ve connected the USB-TTL to the calculator and if the battery is inserted and I turn it off to make the bootloop, the USB-TTL will turn on the red light and blink the green ones. But if I connect it to the PC I get no Input.

With Windows 10 it says an error saying it can´t open the COM Port

So I´ve tried with Windows XP (on a Virtual Machine) and even though it seems it can´t recognize the COM Driver, it actually connects to a COM Port that is detected by HyperTerminal. But sill, no text showing up.

Does anyone know what´s going on?

Forget it.

Just the wrong drivers installed.

For my USB TTL FT232R I followed this guide:
