1.2 OUTPUT TELEGRAMS
Serial port output telegrams may be in either ASCII or binary format. The
binary format is identical to the disk telegram format except for a header (4
bytes) containing both the number of bytes in the telegram (2 bytes) and its
checksum (2 bytes). The checksum is the arithmetic sum of all bytes in the
telegram. This checksum is used by the receiving system to ensure good quality
of data telegrams. Telegrams with a faulty cheksum should be disregarded.
The ASCII format should be selected when the need for reading the data as text
is important. Binary is more compact, and is used for data transfer directly to
computer or via modem (e.g. EP 500).
