Checking for Repeating ASCII-String Data on Auxiliary Serial Port

Learn how to monitor and respond to repeating ASCII data from handheld terminals using Galil motion controllers. This application note demonstrates implementing key-hold detection for continuous jog speed control, configuring communication interrupts for real-time response, and managing serial port buffer operations. The example shows how to use function keys F1-F4 for X and Y axis jog speed adjustment with proper timing control and key release detection.
