I've seen the same thing but not on a $75 Router/Switch. I know our Cisco 2600's have both an analog failover and an optional ISDN failover.
Looking at SMC's sight it looks like some of their routers do sport a com port (well I'll be damned....). I guess it just depends on which router he has. http://www.smc.com/index.cfm?sec=Products&pg=Barricade-Matrix&site=c Garl -----Original Message----- From: Linux Rocks !

I belive if the dsl/cable goes down, the modem dials up... I think efn has a router like this in the office.
