Quite honestly, distributing clocks and resets through the RS-232 transceivers looks like a bad idea.

The DE2 has a external clock input, using a SMA connector. I suggest you use that one for distributing clock to all 3 DE2 boards.

Then work into fitting your remaining needs into the 40 pin headers.

Ie, I suggest you put a debounced push button on your daughter card to generate the RESET and feed it back to the DE2 boards though a pin in one of the 40 pin headers.
