serial communication is over digital IO lines. you can copy IFIs buffers, or write your own. you end up with 16 some odd serial ports (of course, you need to make your own connectors)
the chip by itself runs TTL levels (+5v) for the signal. with serial comunication, most things will cope just fine with +5, (rs232 spec goes to +15v, but we would use +12v), but some things are just pickey. so if you want to be "fully" compatable with all devices, your going to need a RS232 converter chip. any electrionics provider will sell them... you can get 4 converters in one IC for a buck or two
