BOOL tnet_msg_poll (
    U8 session);        /* Telnet Session handle. */

The tnet_msg_poll function polls the upper-layer user application for unsolicited messages. The Telnet session handle identified with parameter session can be used to identify the remote host when several Telnet connections are active at the same time.

If this function returns __TRUE a telnet callback function is called immediatelly to get the message.

The tnet_msg_poll function returns __TRUE when the upper-layer user application has a pending message to send. Otherwise, the function returns __FALSE.
