Here's the official doc:

So there is a lot taken care of directly by the hardware, making it easier.
Here's some relevant info:
Any operation which requires a long operation period and suffers from multiple interrupts such as V-BLANK
should have VECT_COMOFFRTS before the operation and VECT_COMONRTS before reti
command.
VECT_COMGETDATA and VECT_COMGETBUFDATA can go into main.
You could conceivably tap into the serial lines and record what's happening between two systems in a commercial game.
Serial specs:
Communication speed : 19200bps
Bits : 8 bit
Parity : None
Stop bit : 1 bit
Handshake flow : handshake with CTS, RTS signals
