"TFT_Terminal" example: how to adapt to ST7796?

[FerGT50]

Hello,
the "TFT_Terminal" example is very nice and useful (Serial Terminal).

Unfortunately it only works with ILI9341 (320x240) in portrait mode, since it uses the hardware scrolling feature of the controller, with calls like

tft.writecommand(ILI9341_VSCRDEF);
tft.writecommand(ILI9341_VSCRSADD);

Would it be possible to adapt the example to work with a ST7796-based display?
I have a nice 4.0" 480x320 ST7796 which would be very useful as a Serial Terminal.

Any suggestion for a starting point?

Many thanks
