 I<prot> specifies the transport protocol.  It can be one of:

 I<mode> specifies the output mode.  It can be one of:
-  B<ascii> ASCII output with dots for non-printable characters

 Since the output in B<ascii> mode may contain newlines, the length of each section
 of output plus a newline precedes each section of output.
 
-I<filter> specifies the stream to be displayed.  UDP streams are selected with
-IP address plus port pairs.  TCP streams are selected with either the stream
-index or IP address plus port pairs.  For example:

 I<range> optionally specifies which "chunks" of the stream should be displayed.
