I'm having trouble figuring out which FPGA I/O pins are connected to tx0, rx0, tx1, and rx1 for the two RS422 connectors on the 7c81. I don't see any of those pins in the UCF file, so they must be tied to gpio somewhere else. Grepping for TX0 in the *_34.vhd pin files seems to give a variety of I/O pins assigned to sserial tx0 pins (IO 04, 05, 10, 15, 21, 27 according to the comments). I'm missing a link in the chain somewhere.
