What are the two characters for ASC?

• A. ESC and FSC
• B. ASC and FSC
• C. AOC and FSC
• D. ESC and AOC

Answer: (B)

The concept being tested is how data blocks are framed with specific start and end markers. In this scheme, ASC serves as the opening delimiter for an ASC-encoded block, and FSC serves as the closing delimiter. Using this paired set lets a receiver recognize exactly where the block begins and ends, even when the payload inside varies in length or contains other control characters. It provides a clear, unambiguous boundary so the data can be parsed reliably. This pairing is preferable because it creates a dedicated framing sequence that won’t conflict with other control codes that might appear inside the payload. The other options mix different markers that could be mistaken for data or used for different purposes, which would make it harder to correctly delineate the ASC block.
