The baud rate is split between two 4-bit parameters (for compatibility
reasons). If the Baud 1 parameter is 0, then Baud 2 is used. Rates listed in
bold are not available on the Z7340A and Z7350A interface cards.Baud rates
above 76800 are not supported on the Z7200A card and rates above 128000
are not supported for the Z7400A card.
