Okay, I am doing a large (for me as a beginner) project. I am using an Alera DE2 board and basically what I'm going to do is make a decoder for a bluetooth USB that will take signals from a Wii-mote controller and use them to control a wireless RC Car.
I have gone to this site:
http://jbprojects.net/articles/rc/
and he has a wonderful step-by-step guide for how to set this up to a parallel port, but the DE2 board only has a RS-232(serial) port. I'm not too sure how to hook this up to make it work on a serial port. From what I am reading, there are 9 pins on this and i think there are only 2 output pins. I'm a total hardware noob so forgive me if I'm completely wrong on this.
I can figure out the software for it (will probably have to make it in VHDL or C if i decide to put a simple computer in the board) but the hardware part is killing me. Anyone have any suggestions on how best to hook this thing up to the board, serial port or otherwise?
oh here's a link to what the board has on it to be used:
page 7 has the picture of what is on it (its a pdf so slow connections beware)
ftp://ftp.altera.com/up/pub/Webdocs/DE2_UserManual.pdf
DE2 inputs, outputs
In the RC project page linked above, all the printer port is being used for is to switch the RC transmitter in a similar manner as the buttons being pushed. You shouldn’t be trying to make the same type of connection on the DE2 serial port, but should use the IO pins of the DE2. Note also to use the interface diagram on the RC project page to connect the IO pins to the RC transmitter board. Then just program the DE2 board to run those switches to drive the RC car.
BTW, the DE2 pdf manual is not loading. An Altera website problem, I think.
so there should be IO pins
so there should be IO pins on the board for me to connect to the controller then and i should not be using the serial port?
oh and you can get to the pdf from this site to see a diagram of what the board has:

I’ll try to figure out which are the IO pins on it (such a noob lol) and thanks for the info
I’m assuming the IO pins are
I’m assuming the IO pins are in the 2 “expansion header” slots on the right in that picture on page 7 of the pdf thats on the site i linked last post. please correct me if i’m wrong lol, as i said, I’m a total noob
edit: page number
thanks a ton for your help 
thanks a ton for your help
Still cannot download
Still cannot download anything from that ftp server, including getting into the root pub directory. But the "expansion header" should have plenty of pins that can be switched within your program. to then control the transmitter.
