[W0] - Least significant bit of the scroll wheel movement value. [1] - Bit 3 of this #4 byte is always “1”. Sending “0” for this bit will cause the entire mouse control packet to be ignored.

The standard BAUD rates available are 2400, 4800, 9600, 14400, 19200, and 38400. The number of bits in the character sent to the USB-ASC232 may be 7 bits or 8 bits. NOTE: 8 bit characters are required for Ex- tended ASCII and Key Number modes. - Page 16 The “Echo” setting means that the USB-ASC232 will send a one’s complement response byte to each command. For instance, if a value of 0x32 is sent to the USB-ASC232 serial port, it will reply with a value of 0xCD in response. Use this handshaking mode as a way to not only keep the buffer from overflowing, but is also a confirmation of the value of the code that was received.
