By "a serial interface router" I assume you mean a router with two interfaces: one ethernet and one serial.

These are used to provide IP layer connectivity between a LAN (on the Ethernet port) and some kind of WAN (on the serial port).

The WAN could be a point-to-point link - say a leased line with another serial router at the other end.  It could also be something more complicated like a frame relay service.

The router works by forwarding packets between the interfaces based on IP routing decisions.  Put simply, if there is one IP network on the LAN side, the router could say "If the destination is on the LAN side then send it out the ethernet, otherwise send it to the router at the other end of the serial link to deal with".  The PCs on the LAN side would then use the router as their "gateway" to other IP networks.
