The message reference, <mr>, which is returned to the application is allocated by the
product.This number begins with 0 and is incremented by one for each outgoing mes-
sage (successful and failure cases); it is cyclic on one byte (0 follows 255).
NOTE:
this number is not a storage number – outgoing messages are not stored.
