These commands will not function if the serial port configuration for Modbus RTU
or the COM interface configuration for Modbus TCP are set to Read Only in
nanoNavigator.
The ModScan32 request address range is shown in decimal only. The ModScan32
software does not start its addressing at 0 so all decimal ranges shown are offset by a factor
of one, i.e. hexadecimal 0x1000 is the equivalent of decimal 4096, but because of
ModScan32 addressing, the starting address is actually 4097. If using ModScan32 in the
hexadecimal format, then hexadecimal 0x1000 actually equals 0x1001.
