Hi all,

I just ordered one of the above displays a few days ago, and I can successfully display data on it, however I'm having problems reading the keypad. I'm running linux, and did a 'cat /dev/lcd' and used a paper clip to short pins on the keypad connector, I got nothing back (not even garbage data). To make sure the display is working, I tried 'echo "Test" > /dev/lcd' and all worked okay...

Any ideas???

*Sigh*, you were right the first time... User error... make sure that those pins are correct folks! Those numbers are printed on the inside of those DB9 connectors to help you!!!

Thanks for your help!!!
