The maximum block length (maximum length of a telegram segment) can be set using the RESET com-
mand. The default value for the block length is 128. The maximum block length that can be set is 255.
The blocking sequence can be aborted using the RESET command. The blocking sequence will be en-
ded. No further acknowledgement of the aborted command will be issued.
All other commands within a blocking sequence will be rejected by the ASM 421 with an error message.
The present status of the blocking sequence remains unchanged.
