Injector (AT) component
Comms data injector to replicate basic AT command syntax. The component will record each incoming character until the termination character is received. Once this happens the component will respond by echoing back the received data followed by an "OK" reply.
Examples
GSM Example File
GSM Example
Example should show the following on the display on the panel and on the hardware.
The AT injector component allows us to simulate the response of the GSM module.

Property reference
Circular Buffer Size
This property is of type Unsigned integer and can be referenced with the variable name CircularBufferSize.
Amount of room in the circular buffers before running out of memory.
e.g. max command that can be recorded.
