at a command line prompt on the local machine (assuming that the DV executable is in the command path of the shell)

There are no command line options, however one can specify an alternative TCP/IP port number by setting the environment variable "DVPORT" prior to starting DV. This would allow one to run multiple copies of DV on a single machine. For example, to have DV listen for data on port 5010 (the default is 5005):

> setenv DVPORT 5010
> DV
