What exactly does the Logitech C7 serial mouse do on the power-up sequence? I mean, the sequence appears to be, set DTR active, then set RTS active, then wait for something, but for what? 86Box's emulated mouse right starts a timer when that happens, that sends the 0x4D ('M') but Windows 2000 (and it seems Windows NT 3.51 as well) doesn't seem to like that, it seems to be expecting something to happen in the modem status register of the serial port. What does the real mouse do when it's powered up?
