#26 Modbus PLC RTU simulater is not responding

[shn]

When I send a request to write in the registers, I am not getting the response. Comms screen shows this:
RX 01 10 00 12 00 02
RX 04 12 34 56 78 4E
RX 08

i saw one of the posts which says check the CRC. I did that also but still I m getting the same. Can anybody help me with dis??

When I am sending commands to the simulator, if I toggle the port open/close it restarts the server, and will respond properly a few times, but then stops responding, even though the port monitor shows the correct bytes coming in.
if I close and reopen the port, it will answer a few, then go quiet again...
