UniPCemu serial mouse 'problems'?

I notice something odd: UniPCemu generates serial mouse packets, but the MOUSE.SYS(from Windows 3.0) only seems to go up and down? The packets themselves seem 'OK'?

			//Translate our movement to valid values if needed!
			xmove = signed2unsigned8(MAX(MIN(packet->xmove,0x7F),-0x80)); //Limit!
			ymove = signed2unsigned8(MAX(MIN(packet->ymove,0x7F),-0x80)); //Limit!

			if (SERMouse.movement==0) //Not gotten movement masked?
			{
				xmove = ymove = 0; //No movement!
			}
			//Bits 0-1 are X6&X7. Bits 2-3 are Y6&Y7. They're signed values.
			highbits = ((xmove >> 6) & 0x3); //X6&X7 to bits 0-1!
			highbits |= ((ymove >> 4) & 0xC); //Y6&7 to bits 2-3!

			byte p[3];
			p[0] = 0x40 | (buttons << 4) | highbits; //First packet byte!
			p[1] = (xmove&0x3F);
			p[2] = (ymove&0x3F);

signed2unsigned simply executes a typecast by union{sbyte s; byte u;}.

Are those resulting packets correct?

Just tried using the ctmouse(CuteMouse) driver. When running, it detects the serial mouse correctly as a Microsoft Mouse, then proceeds to somehow hang the CPU using a IF=0,HLT state? So there's a serious CPU problem in that driver alone? Maybe also something that's at the cause of the mouse problem itself?

This is a common emulator log of the driver running:

Anyone can see what's going wrong?

Just tried running the cutemouse driver on the 80186 emulation. I then tried running edit.com. The mouse was working fine.
Then I tried firing up the Windows 3.0 setup. Once it entered graphical mode(640x480x16), the mouse was behaving strange again. Does that mean it's actually a CPU problem and not a hardware one?

Oddly enough, except for Windows 3.0's mouse, the mouse functions properly using CuteMouse with the serial mouse, running both edit.com as well as with Microsoft Flight Simulator 5.1(running in 640x400 mode)? So it's a Windows 3.0/MOUSE.SYS-only problem?
