Windows device driver information for Other Logitech Mouse Serial

The Other Logitech Mouse Serial device is a serial mouse device that connects to a serial dialout line RS232/V24. The driver for this mouse device can identify its supported mouse device via dropping the RTS to low and then increasing it again after. Approximately 14 ms later, the device will transmit a 0X4D ‘M’ on the data’s line. After another 63 ms, the Other Logitech Mouse Serial device will transmit a 0X33 or ‘3’. The relative movement of this mouse device is transmitted as ‘dy’ or positive means down and ‘dx’ or positive means right. Different mouse devices can function at varying speeds. When selecting the speed of mouse devices, it has to cycle through 1200 bits per second, 2400 bits per second and 4800 bits per second speeds, every time writing 2 characters and waiting for 0.1 seconds. Meanwhile, a data packet’s first byte may be utilized for synchronization purposes.

This serial mouse device uses Logitech’s Extension protocol. When the Other Logitech Mouse Serial device’s middle button is up, a three byte packet is transmitted. On the other hand, when the middle button is down, a four byte packet is transmitted where the fourth byte has a 0X20 value or a 0X20 bit set at the least. Specifically, when the middle button is pressed, it is reported as 0,0,0,0X20 in the event that no other buttons are pressed. The 3rd button’s state information is transmitted utilizing an extra byte which will be transmitted after a typical packet when required. The 32 (dec) value is transmitted each time the button at the middle is pressed and it is likewise transmitted each instance with the data packet if the center button is pressed down and the mouse device’s data packet is transmitted for other purposes.
