there is a bug in Modrsim. I contacted the author on 8/24/06 but it looks like 
he 
still hasn't fixed it. 

Conrad,

Thanks for the key. I think i may have found a "bug". The response for
writing a single holding register should echo the request. The

mod_RSsim response does not include the last two
bytes (the data).

For example -

TCP/IP request to set register 200 to value 350
000000000006 FF 06 00 C8 01 5E

the actual response
000000000004 FF 06 00 C8

should be
000000000004 FF 06 00 C8 01 5E
