My home network is powered by a cisco 1601 connected to a USR 56kbps sportster via an RS-232 cable. The connection is made to the onboard DB-60 serial interface. It is predominately set up for dialing to an ISP, but I have called into the line from a laptop (with modem) to do testing. You really didn't indicate exactly how you were looking to use this connection, so my assumption is a setup for remote management, or possibly connecting networks via DDR over this line. There should be no problem.
