I see you used "lspci" and the port was not there. Try booting the OS that sees the port then go to /dev/serial/by-id and have a look.Ports there are names for their hardware locations While booted up on that system try lspci. On Mon, Jun 3, 2019 at 6:58 PM Gene Heskett wrote: > > On Mond

A search for de9 to db25 rs232 adapter Turns up many of them for cheap. A computer shop that's been around long enough ought to have one or more laying around, might even give it to you to avoid throwing it away. Irritating that companies for whom cables are their specialty are using the ther

Here is a good serial port guide for Linux. Section 16 is "troubleshooting". THeir first step is to do what I suggested, check BIOS setting before booting. After that, they suggest scanning PCI bus This is the best documentation of serial ports I've seen www.tldp.org/HOWTO/Serial-HOWTO.html O

The best way to test serial ports under Linux (or any other OS) is to make a loopback device.This is a fancy name for a short length of wire that short the Rx and Tx pins. You should then be able to read back every byte you send. It loopback fails then you know the promlem is at your end
