Are you looking for the DB9 connector as a shield?
There is a nice tutorial that explains starting with RS232 on the ND+2:

I'm looking at it for sending some serial messages to a modem through RS232.

Hi Guliano,
we manufactured RS232/RS485 shield for N+ but it is suitable for N+2 too.
COM1: RS485 / RS232, on terminal block.
COM2: RS232TTL / RS232 on DB9
Supply: 9-30 VDC on terminal block
On the shield there are 6 pcs LED for Tx/Rx communication COM1, COM2, ETH, but you can use them for other purposes too.
Regards,
Gyorgy

Hi Gyorgy,
Sorry I missed your post.
As stated in my original post, I am looking for a shield I can mount on TOP of N+2.
I see another cons on the shield your are recommending me and it is having the need of another power source for it.
Anyhow, it might not be suitable for the project I am working on right now but maybe in the future. Please send me the URL where to buy it.
Thank you

Hi Chris,
Hopefully you see this thread
I was looking at both the N+ and N+2 boards closely and it seems that I can use the Cute Digi RS232 Shield on top of the N+2 but just wanted to confirm something with you first:
- I see on the N+2 that between the SD pin and the GND pin there is a blank pin without a name, is that a Aref pin in the N+2 which is the same exact position as in the N+ or not being used at all? If it is not being used at all, I can safely put the Cute Digi RS232 Shield on top of it, right?
- I also noticed, the N+ has a Aref pin in it but the N+2 has a IOref pin in it, are they the same in both boards or they are for different purposes?
This is a picture of the Cute Digi sitting on top of my N+:
Thank you

Chris,
Do you know of any RS-232 Netduino/Arduino shields that also exposes RTS/CTS, DTR/DSR handshaking signals on the DB-9 conector?
Thanks,
Bizhan.
