PC will try to get the ipv6 address from the router at startup address [gateway] CIDR set the PC's ip, gateway's ip and network mask
Default IPv4 CIDR is 24, IPv6 is 64. In the ether mode, the ip of the tapx is the maximum host ID of the subnet.
'ip 10.1.1.70 10.1.1.65 26', set the host ip to 10.1.1.70,
the gateway ip to 10.1.1.65, the netmask to 255.255.255.192, the tapx ip to 10.1.1.126 in the ether mode.
If in the ether mode, please run it before the dynamips loads/starts the ios.
When VPCS started, it listens the ports from 20000 to 20008 and wait the dymamips to connet, and send the packets to the ports from 30000 to 30008 which should be listened by the Dynamips.
VPCS looks for the file named 'startup.vpc' in the current directory, and execute the commands in it if you are not set the startup file from the command line. All the commands in the startup file are the internal command of the VPCS. The line started with '#' or '!' will be discarded.

Dynamips loads ios with NM-16ESW module in slot 1, and listens 30000 to 30002. NM-16ESW is 16 port switch module (from f1/0 to f1/15). '-s 1:0:udp:30000:127.0.0.1:20000' means:
1. this is port 0
2. dynamips (or ios) sends the packets from port 30000 to port 20000 which listens by VPCS (PC1). 3. VPCS (PC1) sends the packets from port 20000 to dynamips.

Note
The cygwin1.dll used by VPCS maybe conflicted with the older or other
versions, please keep the LATEST cygwin1.dll in the your PC.
You should run VPCS before starting the dynamips while using ether mode.
VPCS opens the tap interfaces. And you should know, VPCS will CLOSE the tap interfaces before quit.

vpcs.exe is windows program, only udp mode.
Under linux or OSX, maybe you need chmod +x vpcs. vpcs.osx is OS X program, only udp mode. ChangeLog
version 0.21
1. fix many bugs
version 0.20b
1. make the external tcp server happy 2. fix a bug of the command history function
version 0.20a
1. new 'ping' command with many option
2. new 'set', set local/remote port and pc name
3. new 'save' and 'load', save the current configuration or load the configuration
4. new 'clear' to zero ip address, arp table
5. now, can stop the running command such as 'ping' or 'tr' by Ctrl+C
6. fix the bugs: 'queue is full' and coredump caused by entering the command 'ip' without parameter.
7. support stateless auto configuration, get ipv6 prefix from RA. 8. support save/load the commmand history automaticlly.
And Easter Egg for XV Anniversary Memorial. ^_^
