<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:times new roman, new york, times, serif;font-size:12pt"><DIV>That's exactly what I'm trying to do.</DIV>
<DIV>I've found linux-gpib but it seems that all the logic is in the c files </DIV>
<DIV><A href="http://linux-gpib.sourceforge.net/">http://linux-gpib.sourceforge.net/</A></DIV>
<DIV>and I'm not sure I can take advantage of erlang goodies.</DIV>
<DIV>I'll appreciate if anyone could give me a simple c interface for VISA/GPIB </DIV>
<DIV>and a corresponding erlang code or any advice.</DIV>

<DIV>Thanks<BR></DIV>
