This message implies that your partner is waiting for an RTR message
before it tries to send the transaction again.
bind_cinit_data
This provides the information conveyed on the BIND or CINIT message that
began the session. It enables your application to examine the user-data field.
You see this data message only if the WANT-BIND-DATA PROFILE attribute
is set to USER-DATA or ALL.
flow_control
This indicates that one of the flow-control messages has been received. You
see this only if receipt of flow-control messages is enabled. The data portion
contains two characters, as follows:
RT Resume sending new transactions (SNA RTR)
SM Stop sending new messages (SNA QEC)
QM Message sending quiesced (SNA QC)
RM Resume sending messages (SNA RELQ)
fm_header
The message received from the session partner contains a Function
Management Header (FMH). The FMH usually contains binary data that can
be replaced by periods (.) if the binary data is non-display characters.
interrupt_request
The message is an operator message. The message is not from the session
partner, but from another SNAX/HLS requester using the QMSG facility of
the command interface.
lu_status
The message is a status message from the session partner (an SNA LUSTAT
message).
The hexadecimal display to the right of the data area provides a
convenient display of the actual status bytes.
message_cancelled
The session partner has cancelled the current message. This value can be
received only if LMO is in effect. The previously received message fragments
are to be discarded.
prepared_to_close
The session partner is prepared to terminate the session in an orderly fashion.
You are expected to issue a PREPARE-TO-CLOSE verb.
