+MSTP Capture Tool
+
+This tool captures MS/TP packets on an RS485 serial interface,
+and saves the packets to a file in Wireshark PCAP format for 
+the MS/TP dissector to read.  The filename has a date and time
+code in it, and will contain up to 65535 packets.  A new file
+will be created at each 65535 packet interval.
+
+Here is a sample of the tool running (use CTRL-C to quit).
+D:\code\bacnet-stack\bin>mstpcap COM3 38400
+Adjusted interface name to \\.\COM3
+mstpcap: Using \\.\COM3 for capture at 38400 bps.
+mstpcap: saving capture to mstp_20090729123548.cap

+MS/TP capture tool also includes statistics which are listed for
+any MAC addresses found passing a token, 
+or any MAC address replying to a DER message. 
+The statistics are emitted when CTRL-C is pressed, or when
+65535 packets are captured and the new file is created.
+The statistics are cleared when the new file is created. 
+
+MaxMstr = highest destination MAC during PFM
+Tokens = number of tokens transmitted
+Retries = number of second tokens sent to this MAC
+Treply = max milliseconds it took to reply with a token after receiving a token
+Tusage = max Tusage_delay in milliseconds based on PFM and subsequent token
+Trpfm = max milliseconds to respond to PFM with RPFM.
+Tder = max milliseconds to respond to DER request with DNER
+Tpostpd = max milliseconds to respond to DER request with Reply Postponed.
