Modsoft on DELL Latitude D630

We use Modsoft and edops from a bootable USB stick in DOS.

It works fine on a DELL Latitude D600 notebook. When we use a DELL Latitude D630 notebook, edops works fine, but Modsoft gives the following error message when we load the program to the PLC: "Bad checksum on response Modbus Error Code 120"

It looks like the architecture of the serial port is changed... sinds D630.

Anyone have the same problem or a solution for this?
