I don't see how this can work, since the hostmot2 driver is called 
"hm2_5i20", not "m5i20".

The way the watchdog works may have changed.  There is now a specific 
function that tickles the watchdog.  In halcmd, you can do this:

show all *dog*

and that will list the pins, parameters, and functions with dog in the 
name (hopefully all related to the watchdog ;) )

As I mentioned, you must add the function hm2_5i20.0.pet_watchdog to a 
thread for the card to output anything.

Nope, not until you start petting the dog (they get very needy if you 
ignore them :) )

unlinkp hm2_5i20.0.dac.0.command (or is it value?)
setp [whatever the pin name should be] 1.0
I believe the DAC gain should be set to 1, so whatever number you put in 
is what you should measure on the output.
