Hello.<br>
I have a Cfontz USB LCD 635 working ok with lcd-proc + CFontzPacket
driver.<br>
It displays what I tell it to and menus work fine.<br>
But when I want to receive notification of button presses nothing
happens:<br>
  <br>
  <font color="#0000ff">[eyal@mainmachine lcdproc-0.5.2]$ telnet
127.0.0.1 13666</font><br>
  <font color="#0000ff">Trying 127.0.0.1...</font><br>
  <font color="#0000ff">Connected to mainmachine (127.0.0.1).</font><br>
  <font color="#0000ff">Escape character is '^]'.</font><br>
  <font color="#0000ff">hello</font><br>
  <font color="#0000ff">connect LCDproc 0.5.2 protocol 0.3 lcd wid 20
hgt 4 cellwid 6 cellhgt 8</font><br>
  <font color="#0000ff">client_add_key -exclusively UP  </font><br>
  <font color="#0000ff">success</font><br>
  <font color="#0000ff">&lt;key pressed&gt;</font><br>
  <br>
  <br>
same goes for non-exclusive.<br>
Like I said, menus work fine, so the buttons themselves are not to
blame.<br>
What could be causing this?<br>
  <br>
Thanks<br>

I had the same problem with my 635. I believe the culprit is the fact
that you used "UP" instead of "Up". It claims<br>
that it succeeds, but I had to change my API to use words with only the
first letter capitalized. I believe the<br>
following is a complete list of valid keys for the 635 (taken straight
from my ruby code):<br>
<br>
VALID_KEYS = [ "Escape", "Enter", "Up", "Down", "Left", "Right" ]<br>
