Compacted Format

Description Transaction data can also be output in compacted format, deleting all spaces,

headings, and punctuation. Compacted format is generally used to send

transactions to a computer. The last four digits of each line represent the CRC-16

checksum; a data integrity check. Compacted transactions can be transmitted

two ways: line-by-line, with an acknowledgement from the data terminal or

program after each transaction (Figure 4-4); or as a continuous string (Figure 4-

5).
