3.162.2 Supplied Parameters
The application supplies the following parameter:
opcode
AP_QUERY_TN3270_DEFAULTS
3.162.3 Returned Parameters: Successful Execution
If the verb executes successfully, SNAplus2 returns the following parameters:
primary_rc
AP_OK
def_data.force_responses
Controls client responses on printer sessions. Possible values are:
AP_YES
Requests definite responses.
AP_NO
Request responses matching SNA traffic.
def_data.keepalive_method
Method for sending keep-alive messages. Keep-alive messages are messages sent to TN3270 clients when
there is no other activity on the connection, to keep the TCP/IP connections to the clients active; this ensures
that failed connections and clients can be detected. If there is no traffic at all on a TCP/IP connection, failure
of the connection or of the client may never be detected, which wastes TN server resources and prevents LUs
from being used for other sessions.
Possible values are:
AP_NONE
Do not send keep-alive messages.
AP_TN3270_NOP
Send Telnet NOP messages.
AP_TN3270_TM
Send Telnet DO TIMING-MARK messages.
