FW 4.5 allows to use command “prunf N”, which starts automatically script on N-th position. Future version should be able to start any scripts via its name if present. Also SDK implements standard function “printf(…)” which outputs formatted text to shell line. So this output, even originally designed as debug function, can be parsed by external program. At this moment there is no line that would allow to send message to the script, but it is planned for next update.
