We're busy building a device for polling energy meters over RS-485, and one of my colleagues asked if it were possible to use the activity LED on the unit to indicate RS-485 activity. Presently, I use it to indicate mmc0 activity. I'm not sure if there's an equivalent for serial ports. I did a bit of searching, both for general purpose serial triggers through to auart-related triggers, nothing seemed to show up. On a related note, the FlexCAN driver supports turning on/off regulators when someone brings up or down a CAN interface. Is there an equivalent facility on mxs-auart that would turn on a regulator when someone opens a serial port?
