Hi Mark,
Can anybody say whether there is a good reason that serial.pp lacks a
function to read the CD signal?
i would recommend the synaser library, more sophisticated then the serial.pp
http://www.ararat.cz/synapse/doku.php/download
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.
Is SerFlush, which calls fpfsync, intended to discard input data, output
data or both?
don't know in serial.pp
In synaser AFAIK on Linux only the transmit buffers, on Windows RX and TX
Mit freundlichen Grüßen
Markus Greim
