Space is always 0, mark is always 1.

Assuming the "8" means "8 data bits", 8/even describes a nine-bit
transmission format (actually, in asynchronous mode it will be 11 bits
due to one start and one stop bit per character).

Digital Press used to sell a good intro to data communications
by McNamara.  I don't know if it's still in print.
