everything that you store in port 2 is lost just because the file "rom.49g" is READONLY.
Since version 2.0, it is now possible from the menu to manage the Flash ROM file (it will fully replaces the ROM).

you should be able to see it in the Emu48 settings.
It is still experimental and I see some issues when sending characters from the emulator to a real HP48 or HP49 with the kermit protocol.
For the moment, the communication has been artificially slowed down in this direction.
If the adapter is unplugged then plugged back in, you may need to call OPENIO/CLOSEIO.

Version 2.3 (2021-09-xx)
- Add the serial port support (via USB OTG).
FIX: When stop the app, Serial exception seems to delay the save of the calc state!!!!
FIX: Inform if the connection is not possible.
FIX: No 'No driver' on real device
FIX: ID change -> replace id by vendor:device ids?
BUG: From Windows to Android with HP49G QINHENG CH340 -> all character at once bug
No issue with Prolific PL2303GT3
Not reproducible!
BUG: When openIO on real device, 1st OPENIO failed, 2nd OPENIO succeeded
TEST: With real HP48SX
TODO: Check the self test about UART
- Add an experimental serial port support (via USB OTG).
- Show KML log on request.
- Allows pressing a calculator button with the right button of the mouse and prevents its release to allow the On+A+F key combination (with Android version >= 5.0).
- Update the embedded help file "Emu48.html" to the latest version.
- Open an external web browser when you click an external links in the Help.
- Add Real blue 50g faceplate based on Eric KML script.
- Add Real blue 50g faceplate based on my calculator and on the KML script from Eric Rechlin.
