Which characters are sent by the ship station to indicate a desire to send a message via a direct connection to a shoreside TELEX subscriber?

Correct Answer: Option B — DIRTLX0xxyyyy+

The command 'DIRTLX' followed by the destination number and a plus sign is the standard protocol for establishing a direct telex connection. This instructs the coast station to route the call through the public telex network to the specified subscriber's terminal.
