In 400d, the "sendtointercom" func is very import. because we use it to change setting, just like iso, wb...
but in 450d, i can't find this func, seems it use "prop_request_change" to change property and make setting changed. I think canon encapsulated the sendtointercom func, but can't find anything to prove it.
In ml, we use "prop_request_change" to change setting.
for gui initialization, 450d is like 500d , a big change with 400d.
so if we want to run ml or 400dplus on 450d, we must solve this.
