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