Optimize 3270 data streams with CICS OTTO

IBM® CICS® Online Transmission Time Optimizer for z/OS® (CICS OTTO) improves user productivity and increases network utilization through 3270 data stream optimization. It reduces the number of characters transmitted to supported devices by making optimum use of all available orders for each device type. It keeps the screen layout of conversational terminals in memory so that only changed data is transmitted. CICS OTTO can also reduce the contention between the devices on a communications line and between devices connected to local controllers to improve response times.
