I have a very simple testing in RTEMS 4.8.0 with a PC486 plateform, and it works OK. I attached it here and maybe someone is interested in it. <br><br> TO build it :<br> 1. download freeMODBUS package from it's website www.freemodbus.org, the version now is 1.3.0<br><br> 2. release freemodbus in a directory, and then build a new subdirectory "RTEMSi386" under the directory \demo<br><br> 3. release the atteched files in \demo\RTEMSi386，then MAKE it<br> <br> To test it：<br> run \demo\RTEMSi386\o-optimize\MODBUS-demo.exe in a PC computer plateform, it will use COM port 1 as MODBUS port. the serial port setting is : 38400,8,E,1, no hardware flow control; and MODBUS address is 0x01;<br><br> the demo can only response for Input registers, there are 4 registers which start address is 0x1000.<br><br> <br> Enjoy it, thank you.<br><br> <br><br /><hr />用 Windows Live Spaces 展示个性自我，与好友分享生活！ <a href='http://spaces.live.com/?page=HP' target='_new'>了解更多信息！</a></body>
