unsigned char __fastcall__ revers (unsigned char onoff);
If the argument is non zero, the function enables reverse character display. If the argument is zero, reverse character display is switched off. The old value of the setting is returned.
- The function may not be supported by the hardware, in which case the call is ignored.
- The function is only available as fastcall function, so it may only be used in presence of a prototype.
