Which of the following keystrokes or characters follows most commands in ARQ communications when working an automated Coast Station?

🔍 Key Concepts

• ARQ (Automatic Repeat reQuest) protocol used in maritime radiotelex / NBDP with Coast Stations • How operators indicate the end of a command and hand over transmit/receive control in automated Coast Station operation • The difference between plain-text keys (like ENTER) and specific ARQ control sequences or prosigns

💭 Think About

• Ask yourself: in automated ARQ coast station working, does the system need a simple line break, or a specific control signal that the command string is complete? • Consider what signal the equipment manual usually shows immediately after a command entry in examples of calling or working a Coast Station. • Think about which option looks like normal keyboard use, and which looks like a standardized radiotelex sequence for controlling the link.

✅ Before You Answer

• Verify which symbol or sequence is shown in typical ARQ telex command examples right after commands to an automated Coast Station. • Check whether the correct choice is something you would normally use in regular typing (like on a computer) versus something designed specifically for radio telex control. • Confirm that the option you select matches actual radiotelex / NBDP procedural examples, not just what "seems logical" from everyday computer use.
