Reset - TDK Module blu2i User Manual

Future enhancement may allow the BREAK signal to be used to map to
GPIO which with appropriate external hardware may allow for a BREAK
to be reproduced on the TX line.

The module can be reset by the host without the need of any I/O using a
BREAK signal. The module has been configured to reset when the RX
line detects a break condition for durations greater than 100
