# 
# SYNOPSIS
#      ptregshow [slot/]port

# DESCRIPTION
#      This command will display the contents of port registers.
# 
# OPTIONS
#      [slot/]port
#                Specify  the  index  of  the port within the blade
#                specified by slot to be  displayed.  If  slot  not
#                provided,  the  current  slot will be assumed. You
#                can set the current slot by execution  of  setslot
#                command.
