# NAME
#      ptchipregshow - dump chip based register contents
# 
# SYNOPSIS
#      ptchipregshow [slot/]port
# 
# AVAILABILITY
#      all users
# 
# DESCRIPTION
#      This command will display the contents of chip based regis-
#      ters.
# 
# OPTIONS
#      [slot/]port
#                Specify the index of the  port  within  the  blade
#                specified  by slot to be displayed. If slot is not
#                specifed, the current slot will  be  assumed.  You
#                can  set  the current slot by execution of setslot
#                command.
