<p>Dear Jef,<br /> <br /> <<> There is almost no documentation other than the libdivecomputer source code. Why <br />> do you need it?>><br /> <br /><br /></p>
<p>I realised that talking to theVEO2 is as simple as talking to a com port.</p>
<p> </p>
<p>I considered writing an interface to talk to the VEO in C#.</p>
<p> </p>
<p>How did you found out about all communication protocol ? ( reverce engineering ? )</p>
<p> </p>
<p>I'm amazed !!</p>
<p> </p>
<p>Thanks,</p>
