Cannot find signals in Mesa 5i25

I've just started working with a Mesa 5i25/7i78 set up. I've got used to using Show hal configuration with configs created for the parallel port. With the parallel port set up its easy to use Show Hal Configuration to find out whats connected to what in hal, ie check pins, and the signals that link them. I cannot find signals that link to the gpio pins in the Mesa 5i25. I don't have any problems with my cards, they are new and set up ready to use. I realise that the base thread type components run on the 5i25 card, but is it possible to see all the pins/signals/functions etc as you can in the simpler parallel port configs.

halcmd show pin hm2*

should show all the available 5I25 hal pins though some possible pins
may not be created depending on the configuration string in the loadrt hm2_pci line

Thanks for that. Is it possible to see which 5i25 hal pins are connected to signals. The pins shown in Show Hal Configuration don't seem to have any signals associated with them.

halcmd show all
will show everything (pins, parameters, signals, thread and functions)
