IOS Feature question [7:62797]

[Ed Dial]

Ladies n' Gentlemen, a quick question about the IOS feature set. Does 
anyone know of a way to configure an async serial port (either a sync/async 
WIC or the 8/16 port NM) on a 3600 platform to act as a point-to-multipoint 
FRAD? The application is for SCADA, so a single RS-232 based PC at 1200 bps 
needs to poll all devices (also RS-232) on the network simultaneously in a 
classic point-to-multipoint topology. All devices listen to the poll, but 
only the unit with the correct polled address will respond to the PC in a 
round-robin fashion. I have 30 of these RTUs, or SCADA devices scattered 
around all points of a frame-relay network. I would like to pull this off 
in the 3600 without having to add 2500s to the stack. Mapping an async port 
directly to a DLCI would be good. My lab only has async on a 2511 (other 
than AUX), so I can't experiment with it. Any ideas?

Thanks in advance - Ed

Another thing to consider about the 2950's, which may or may not be 
important to you, is they do not support ISL.
