Kirk I thank you for the offer for the r485 converter. I think after reading some of the posts I would rather go with full duplex. Paying you for, and shipping, it would have been a pain too I think, as I am in Canada. I came across a web site with a Modbus library that is GPL. http://copyleft.free.fr/wordpress/index.php/libmodbus/ In his trunk version he is working on a slave protocol - if I could get this working I could set up two computers with rs 232 and test. prob test classicladder too. The big but is that I cannot figure out how to auto make the program . I downloaded automake and autoconfig but it doesn't work and I don't know how to trouble shoot the process. Any help would be great from anyone. Just thought it might be interesting to peruse or even use for your work. Thanks again.
