This error is modbus-serial telling you that receives less information that it was expecting. How you have setup the communication in Fuxa and in Modbus poll? Are you able to provide wireshark data captures for both cases?

Hi, I added the possibility to set a frame delay that maybe can help (in master branch), would be nice to try and give me feedback
