With wireshark how can I monitor packets that are coming and going on the serial port of a Cisco router 3945?

You can monitor the traffic from the ethernet side, but in that case it is framed in ethernet. To get hdlc or ppp you will have to somehow tap on the serial side. Wireshark integrates nicely into GNS3 (even on serial links) if you are wanting to play around without a serial tap.
