Does anyone know how to get a serial mouse working in a 16-bit operating system? I have PS/2 working (see attached file) but PCEM has (serial) after the device name for quite a fewer ROMs and the int 15h fails no matter what order I put them in.

Hi Robert,
It's been a long time since I did some mouse stuff in MikeOS (probably
13 years ago). Is your mouse.asm the complete support for PS/2 mice? I
implemented PS/2 at one point but my code was much longer (and
messier) so I removed it. If yours works, maybe it's something we can
add to the next major release – looks nice and clean...
Cheers,
Mike

I've only done minimal testing at the moment but it seems to work so far (see attached screenshot). There may be some other stuff to do but I'm not sure at the moment. In qemu I have no problems so far (I haven't tried using the coordinates yet though) but it doesn't work in pcem or 86box as they have serial after the device name so I'm assuming that they are using serial mouse emulation but I don't know how to interface with it as most of the stuff I find is usually for 32-bit OS's.

Hey all,
Just a little update I finally got both PS/2 and serial mice working (at a basic level) so I've attached two files to this message. Each one has what type of mouse the code works with in it's name so feel free to include the code in any projects (with modifications to make them useful).
