MiNET message general format
Several values of the initial message type (MT) octet are reserved as extension codes (see § 3.3). The
presence of these codes indicates that the MT field extends into the next octet (octet 2).
Variable length messages are assembled as required. The maximum message length is limited by the data
link layer to 260 octets, however specific terminals may only allow significantly shorter messages due to
buffering constraints.
