Logitech DOS driver (mouse.exe)...
...It has a "9600" option to set the rate to 9600 "if possible" and apparently isn't possible on the mouse I'm using.
You can read a quite detailed technical explanation here... this 9600bps option is supported only by a few Logitech mice.

Yes I didn't mean to imply it was a physical limitation of RS-232 serial. But other than some specific logitech hardware (and their specific bespoke drivers) there is basically zero support for faster serial mouse interfacing
My personal experience with my mice (serial and PS2 compatible, various models, with and without cord) is different.
I only changed the serial port speed to 19200 bps using the DOS MODE utility, and mice just accepted that new speed, even without echoing the according "*<char>" speed selection code to the mouse port.
I did not like Logitech mice since their inception, because they were so jerky, and they stopped working when setting the serial port to a higher speed.
