The Boxsoft-Entermice mouse system only works on graphic screens, this is a fact.
But.... hypothetically speaking... on a text screen an easy implementation of the mouse can be to associate the pointer to the cursor. The EXOS Editor seems being already designed for that purpose, with its scrolling capacities and the free movement of the cursor.
Even it is unnecessary to draw the pointer sprite! It is the most complicate task of the driver.
And, if the mouse driver integration on EXOS is achieved we could have Basic, WP, EXDOS and ISDOS mouse controled....
