Serial Command Line Interface
The MTK test fixture implements a text-based protocol over an RS232 serial port to provide both a
configurable standard test and script-based testing.
All commands listed under the standard test set a configuration value that is stored in nonvolatile
storage. All remaining serial commands only affect the current setting and are not stored (reset
across power cycles).
describes the serial port protocol in the PC to test fixture direction.
