1: Configured for 8-bit word length and 1 stop bit.
2: For multiple command actions, the bits in W1 may be OR’ed.
3: LBM is configured as DTE.
4: If ACK/NAK is selected, and the input sentence is accepted, the ACK will be
put out at the new settings.
5: Present LBM oscillator (20 MHz) will not support 115200 baud.
