Basically the Windows 3.0 driver is dumb enough to not look for alternate serial ports configuration. So my COM1 port was set at 3E8h when it should be 3F8h.

Oh man! ^ This just saved me! Thanks and be well, fellow retro dude!

To be helpful to others (maybe someday):

1. Don't forget to disable your DOS mouse driver / create a boot menu
2. Three-button mouse goes with Mouse Systems driver
3. 3F8/IRQ4!

If just one person could be helped by this, then it was way worth it.

Best regards!
