+ Sending RTR frames is not supported and will be dropped silently.
+
+ Receiving RTR with DLC 8 will appear to be a regular frame with
+ the last received frame's DLC and payload.
+
+ "``AT CSM``" not supported, thus no ACK-ing frames while listening:
+ "``AT MA``" will always be silent. However, immediately after
+ sending a frame, the ELM327 will be in "receive reply" mode, in
+ which it *does* ACK any received frames. Once the bus goes silent
+ or an error occurs (such as BUFFER FULL), the ELM327 will end reply
+ reception mode on its own and elmcan will fall back to "``AT MA``"
+ in order to keep monitoring the bus.
