Class COM_ABSTRACT_SETTINGS

-- Device baud rate

-- Number of bits per data word

-- Parity scheme in use for received and transmitted data

-- Number of stop bits per data word

-- Is other attached to an object considered equal
-- to current object?

-- Check receive data for parity errors?

-- Is a_baud a valid baud rate? True only indicates the
-- operating system supports this rate. The device may not.

-- Is a_data_bits a valid data bits setting?

-- Is a_parity a valid parity setting?

-- Is a_stop_bit a valid stop bits setting?

-- Set is_parity_checked to a_value

-- Converts a_baud_rate in symbols per second
-- to a baud rate setting

-- Converts a_data_bits in number of data bits to a data bits setting

-- Converts a_parity_char to a parity setting

-- Converts a_stop_bits in number of stop bits to a stop bits setting

-- Initialize this object with settings from dev.

-- Set baud_rate with a_baud_rate

-- Set data_bits to a_data_bits

-- Change all settings to default values.
-- Useful to remove any esoteric settings
-- that might be effecting communication

-- Set parity to a_parity

-- Set stop_bits to a_stop_bits
