SENDDATA Verb

Note that the completion of the SEND-DATA verb depends on the session BIND. If
the session is bound with immediate request mode and definite responses are used,
the SEND-DATA verb completes when a response has been received from the session
partner. (If two APS sessions are communicating through a loopback, the message is
received by a RECEIVE-DATA verb.) If the session is bound by any other BIND or
definite responses are not used, the SEND-DATA verb completes when SNAX/HLS
delivers the message to the Tandem SNA access method (for example SNAX/XF).

SEND-DATA Request Screen Description
SESSION-ID
Is the session ID of the current APS session. This field is assigned automatically by
APS and is not modifiable by the APS user.
Prepare to Rcv
(PREPARE-TO-RECEIVE-IND)
If the session is operating in a half-duplex flip-flop send/receive mode, a value of
Y sends the SNA indicator CDI (change direction indicator) with the current
message. This effectively puts your session into a receive state. For optimal
