-BT 1/2/3
This parameter changes the default for the break signal. The default for
DSA200 is ‘Attention 1’ (-BT 1), with ‘Attention 2’ (-BT 2) used in special
circumstances. The default for DSA300 is ‘data attention’ (-BT 3). Data
attention is normally negotiated when needed by the mainframe, and this
parameter is not necessary.
-CM xxxx
qsim -li dsa -cm TWAI
This parameter sets a connection mode to be suggested to the other party when
the connection is initiated. Four connection modes are supported:
TWSI
Two Way Simultaneous Initiators turn. The applications can send
without having 'turn'. The application establishing the session starts.
TWSA
Two Way Simultaneous Acceptors turn. The applications can send
without having 'turn'. The application accepting the session starts.
TWAI
Two Way Alternate Initiators turn. The applications must have 'turn' to
send. The application establishing the session starts.
TWAA
Two Way Alternate Acceptors turn. The applications must have 'turn' to
send. The application accepting the session starts.
By default the handler offers to do both TWS and TWA and leaves the initial
choice of turn to the other end. When Gline receives an incoming connect it
accepts whatever the other end suggests unless you set the -CM parameter.
