I am developing an application which will be run on INTERACTIVE 386 UNIX 
systems which have a Microsoft serial mouse connected to a serial port.  

I understand that there is a /dev/mouse device driver that can be used with 
bus mice and that there is a /dev/kdmouse device driver that can be used with 
keyboard mice (such as exist on a PS/2 system).  These devices are accessed 
with a simple ioctl call that returns information about the button status and 
mouse movement since the last ioctl call.

However, in order to support the Microsoft serial mouse, I believe that I will 
need to communicate with the mouse through /dev/tty00.  As I understand it I 
will need to open the device and send protocol of some sort to the mouse which 
will cause it to send back information about button status and mouse movement.



Questions:

1)	Is anything which I said above wrong?

2)	Is there any sample source code available which could assist me?

3)	Microsoft Press offers a book entitled "Mouse Programmers
	Reference Guide".  Has anyone seen this book? Does it contain 
	information on the protocols used to access the mouse or does it only 
	document the DOS interrupts that are used the DOS TSR mouse driver?

4)	Are there any other sources of documentation that I should
	look into.

5)	Any other suggestions or information that you could offer...
