Usage: %1!s! [pattern=]
             [mask=]

Parameters:

       Tag                 Value
       pattern           - Pattern on which to break in the debugger.
       mask              - Mask that specified which bytes in the
                           pattern are set.

Examples:

       %1!s! "4500" "ffff"

       The command adds a pattern so that any packets with 4500 as the
       first two bytes in the IP header (all IPv4 packets) cause a
       break in the debugger.
