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.
