Technically, one baud is one symbol per second. A 9600bps modem is a 2400 
baud modem with 2 symbols per baud.

One or two start bits to synchronize, one stop bit (or sometimes 1.5 stop 
bits) to process, and perhaps a parity bit. No error correcting bits, but 
parity might give you error detection if you're lucky.
