About the Data Response Timeout (VT/ANSI)
In 3270 SNA and 5250 SNA screen mapping, the host application locks the terminal
keypad while it is busy. When the keypad is unlocked, the host application is ready for
the next action, such as another script command or keystroke. In VT/ANSI screen
mapping, the terminals do not know when the host application is ready for the next
action.
The Data response timeout field sets the amount of inactivity time the DCS 300 waits
before it assumes that the host is finished sending data. That is, the DCS 300 listens on
the TCP/IP socket and if there is no activity and the timeout period expires, the
DCS 300 performs the next action. However, there is no guarantee that the host is
finished sending data.
Note: The DCS 300 may not wait the entire timeout period if an action is performed
successfully. For example, the
PUT_TRANS_FIELD
command waits until the cursor is at
the field location or it may wait for the data response timeout to expire, whichever
comes first.
You set the data response timeout field when you set the script options. Use this field to
tune the DCS 300 to your network environment. If you set the data response timeout too
long, it will affect DCS 300 performance because your throughput will be slower. If
you set the value too short, you may experience timing problems with your host.
