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.
