Say Y here if you have dumb serial boards other than the four standard COM 1/2/3/4 ports. This may happen if you have an AST FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available from https://www.tldp.org/docs.html#howto), or other custom serial port hardware which acts similar to standard serial port hardware. If you only use the standard COM 1/2/3/4 ports, you can say N here to save some memory. You can also say Y if you have an "intelligent" multiport card such as Digiboards, etc.
