i would recommend the synaser library, more sophisticated then the serial.pp


there is a function getCarrier, i guess this is what you need.

If you are working on a ARM system you have to modify some lines in 
synaser. Please check my previous messages.

don't know in serial.pp

In synaser AFAIK on Linux only the transmit buffers,  on Windows RX and TX
