The destination port for the modem at the host needs to match
the device port (*DPORT) in use on all the modems at the
remote sites. For example, if the remote modem’s device port
(*DPORT) is “12345”, then the Modbus host modemʹs S53

Take note of (or set) the Device Port setting in *DPORT to
configure the destination port on the remote modems.
