Modbus server request callbacks. Passed to nmbs_server_create().
These methods accept a pointer to arbitrary user data, which is the arg member of the nmbs_platform_conf that was passed to nmbs_server_create together with this struct.
unit_id is the RTU unit ID of the request sender. It is always 0 on TCP.
