Ubuntu

Old progam needs a com port.

Asked by Tom Koller

I have an old application to reprogram an old cars control modules. It uses a USB cable interface. The cable is recognized as a usbserial device by the OS. But the program, written in the days of Ubuntu 10, needs to see a Com 1 to 4. I am running Ubuntu 16.04.

Bus 001 Device 002: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter

What is needed to translate to the program?

If you reboot with the device detached from the system and log in. Let the system settle then connect the cable. Open a terminal and run:

dmesg | tail ; lsb_release -a ; uname -a

What is the output please?

Thanks

Thanks for the response. I've done what I could find. Nobody talks 'com' any more. Here is what you requested.
