This VDE Protocol Format may be used by applications that use VDE stations to transfer 6-bit ASCII encoded text. The text can be sent over VDE-TER or VDE-SAT as broadcast or addressed message. The parameter, “acknowledge required flag”, should be set to 0 when broadcast is used.

When long text strings are sub-divided, an 11-bit “text sequence number” is used. The text sequence number is used by the originating application to sub-divide the text and by the recipient application to re-assemble the text. The text sequence numbers for each sub-division should be selected to be contiguous and always increasing (110, 111, 112, …). If longer text strings are being transferred, the text sequence numbers should be chosen to associate correctly the sub-divided text with the correct text strings. For international compatible text or authentication / encryption, other VDES messages are defined below.
