Is there a way that one can use to list the actual serial ports

That is, is there a class/method or such already coded to give me a
list of com ports when called?
The com ports are differently named in Windows and Linux, but it
should be possible to get a list of ports actually available.
But not using a listing of dev with ttys in the name, because I have
found that in my test Linux systems there are always 4 of these even
though there is only hardware for a single port...
I haven't found a very good way for Linux. I modified the SynaSer Linux
code for the GetSerialPortNames function in the code on this page:
http://www.turbocontrol.com/simpleserial.htm
Here is what I scan on Linux:
ScanForPorts( '/dev/ttyS*');
ScanForPorts( '/dev/ttyUSB*');
ScanForPorts( '/dev/ttyAM*'); // for ARM board
Are com ports on ARM based embedded Linux named 'ttyAM1', 'ttyAM2'
etc?
It depends on the driver which the port uses. Besides ttyS*, ttyUSB* and
ttyAM* I've also found ttyAMA*, ttyPSC*, ttySAC*, ttyUL*... (but I can
only use the ttyAM* ones on my ARM board... the others where created by
a static /dev creation)

Sven
