Configure an Ethernet interface on each router, put them in a bridge
group, enable the serial interfaces only for bridging and see if you can
ping.
If not check that you have the same bridge group on all interfaces,
defined the spanning tree protocol, and included
a frame-map bridge <dlci> broadcast statement on the serials if the
serials are multipoint.
Debug with show span to determine that BPDU's are being exchanged. Use
show bridge to verify traffic being sent and received.
HTH, post configs if there is still a problem.
