All ports not visible

[goranpop]

On linux i have 8 ports RS232 card and see only 4 ttyS[0,1,2,3]. Is there any config param that i have to set or ?

I found the first problem. Driver in Advantec card was old. Now open and close port is working when i use SerialPort.getCommPort("/dev/ttyS7").

But SerialPort.getCommPorts() still list only 4 ports.

Can you reply back with the results of running the following command:

cat /proc/tty/driver/serial

Thanks!

$ cat /proc/tty/driver/serial (show only 4 ports)

Thanks for the detailed output...that was extremely helpful! It looks like the Advantech card isn't registering itself as a serial port driver in the same way that Linux is expecting. I added a force search for Advantech-specific ports, so please try the following library version and see if it works for you:

If so, please comment back.

It's working, thank you very much. It was essential for me to leave rxtx old lib.

[hedgecrw]

No problem. This fix will be included in the upcoming 2.4.0 release.
