Is there a way to list the available (working) serial ports on a Linux platform like the RaspberryPi?
I would like to offer a dropdown list of working serial ports to the user to select among, but I am dissuaded from it when I do the following: ls -la /dev/tty* It returns a very long list of serial devices and most of these are probably not even existing in real life. On an RPi I get /dev/tty /dev/ttyN (where N=0..63 /dev/ttyAMA0 <== This is RPi Serial0 port on the pin header. /dev/ttyprintk and: /dev/ttyUSB0../dev/ttyUSB3 depending on what is plugged into USB All in all about 70 devices, but not sure which are actually available for use. Is this an impossible task or can one check for "live" serial ports only? If so how? On Windows I have ported a convoluted function from Delphi, which uses Registry reads to give me the list. -- Bo Berglund Developer in Sweden -- _______________________________________________ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
