I'm trying to make my Stratix II (EP2S60F1020C4) communicate with the 
Miniceptor (WJ-8607A) through RS-232.

I am able to communicate with the Miniceptor from the computer using 
Hyper Terminal without a problem, communication between the FPGA and the 
computer is absolutely fine, but the FPGA and the Miniceptor cannot 
communicate properly between themselves. I have tried to send commands 
from the FPGA to the computer, and I receive exactly what I am supposed 
to. I've also send words directly from the computer to the Miniceptor 
and the chip receives commands without fault. But when I send the same 
words from the FPGA directly to the Miniceptor, the Miniceptor does not 
recognize the sent commands.

I've already made sure the voltage levels of the signals match 
specifications on both sides, and I've analyzed the sent words using a 
logic analyzer. Everything appears to be in order, I'm sending what I 
should be, but the Miniceptor just won't recognize it.

Any suggestions! Time is of the essence, any help is appreciated.

Thanks!!
