Mouse driver for Portable Plus

[rprosperi]

AFAIK, DOS 2.1 never supported a mouse, did it, I thought that came with DOS 3.0, but could be wrong.

And even if so, so few people had them at the time, that it's unlikely much software would utilize a mouse, certainly PAM and 1-2-3 (Portable versions) didn't, they're very much cursor oriented.

From curiosity, which programs are you using on the PP that uses a mouse?
