Allow cursor behaviour to be read #196

Open stevesims opened 4 months ago

stevesims commented 4 months ago

On Acorn systems, cursor behaviour could be read using OSBYTE &ED

We should consider adding a mechanism to read the cursor behaviour and send it to MOS

NB currently there is no room in the VDP protocol for this information - we can probably use the remaining VDP protocol bit to indicate some kind of "extended info packet".

Support will be needed in MOS for this behaviour

RISC OS systems included VDU variables that could be read in BASIC using the VDU statement as a function, i.e. var% = VDU var. we should look to incorporate this kind of functionality - this may extend beyond just reading cursor behaviour
