Cher Arnaud,<br>
</blockquote><div><br>Hi Spiros,<br> <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
I send you a demo that reads info from an Emerson Liebert<br>
GXT2-10000T230 through the RS-232 port. This uses the "ESP-II (ESP 2)<br>
Protocol".<br>
Current supported data includes: measurements (voltage, temperature,<br>
etc) , ID strings (serial number, etc), status flags (inverter on,<br>
bypas on, battery charging, etc).<br>
As usual, the original vendor software is in java (Multilink), and really sucks.<br>
I saw in your acknowledgment pages that you have "serial test boxes"<br>
donated from liebert.<br>
</blockquote><div><br>well, that donation was to Russell, and goes back many many years ago...<br> <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
The program I send you is more complicated than needed, to be able to<br>
support more commands in the future.<br>
<br>
1) Can you make the driver?<br>
2) if not, can you point me to a similar driver that I can copy?<br>
<br>
the protocol seems to include a lot more of useless status commands,<br>
unsupported by my ups, but these seem more than enough for a start.<br>
</blockquote><div><br>well, I personally won't make the driver (no hardware and no time).<br>but we can help you in doing one, and it's not that hard.<br>
<br>have a look at the following docs:<br><a href="http://svn.debian.org/wsvn/nut/trunk/docs/new-drivers.txt?op=file&rev=0&sc=0" target="_blank">http://svn.debian.org/wsvn/nut/trunk/docs/new-drivers.txt?op=file&rev=0&sc=0</a><br>

I've seen in the header that you based your work on this:<br><a href="http://www.csc.liv.ac.uk/~greg/projects/liebertserial/">http://www.csc.liv.ac.uk/~greg/projects/liebertserial/</a><br>maybe the author would help you, or join the project?<br>
