ZNet 2.5 send copy of i/o pins


Is it possible to have firmware written that sends a copy of the pin levels to another module by not using API? I need a module that will simply tell the other module to change an i/o pin level to tell a remote processor to wake up and receive serial data. I then need a command to tell it to change back so the processor can sleep again. The sleep function for the modules seem to be an alternative but do not want to have the base wait for the remote to wake. Any suggestions would be greatly appreciated!
