I had fixed a new serial port to my workstation and following the instructions to install the driver for that card, the instructions says:
<1>-copy pci60806a.o to /usr/sbin
<2>-Add /usr/sbin/pci60806a at the end of the /etc/rc.d/rc.local.
<3>-reboot

I had copied the file to /usr/sbin directory but I don't understand step 2
please can anyone explain to me what is the meaning of that?
I opened rc.local file, should I add /usr/sbin/pci60806a to the script? if yes what should be the file name because it gives me save as only

You don't tell us (still) what version/distro of Linux you're using or what hardware it's on. You also now don't tell us what the 'new serial port' is, where you got it, or what instructions you're reading. That file may not exist on your distro, and if you want that program to run automatically at boot time, there may be another way. You have not followed up in either of your other threads, and there is probably VERY little reason a standard USB to serial device won't work.

I don't know how to find out my Linux version
the instruction and the file from drivers CD that came with the RS232 PCI card
USB-Serial port is not working for me

There are good and crappy USB to serial adapters. Get a good one and it will work.
But since you already have a PCI card, how do you know it is not working and needs some extra driver?

when I go to device manager I can see a question mark on that card

I use a terminal command.
sudo nano /etc/rc.d/rc.local

Then type at end of file

/usr/sbin/pci60806a

Ctrl x then Ctrl c (It says at bottom.)

I have to say it seems odd though.

what should I name the new file? because I cannot save the file, I have to use Save As

Then how did you install it? Typically you'd go to a website like Ubuntu, Mint, Debian, etc....THAT is what kind of Linux you're running.
...and you *STILL* don't say what the brand/model of that is, where you got it, etc.
..which takes us back to your first thread where you were told that "not working" doesn't tell us ANYTHING. You were given several suggestions in that thread that you didn't acknowledge or tell us the results of. We aren't going to guess, and we shouldn't have to keep asking you for information. If you want help, provide details, it's as simple as that.
"Device Manager"?? Question mark?? Sounds very much like Windows....where did you click on this device manager program?? How did you access it??
You save it as the filename that YOU POSTED..you are the one who posted those instructions that not only contained the file name, but the path. If you can't save it, then you're not root or have sudo rights, since you're trying to save into /etc. And given that you're putting a program file into /usr/sbin, you can probably just execute that file from the command-line without rebooting.

Given what (very little) you've told us, the instructions seem outdated, and the hardware you're installing probably is as well. Again, there is no need for it, as USB to serial will most likely work. And even *IF* you get this hardware to work, you are going to be right back where you started with the USB to serial device...because if you don't CONFIGURE the serial port, it WILL NOT WORK. You don't just plug in a serial line and sit there...you need to configure it. And you still haven't answered those questions from your other thread, despite being told about minicom, stty, and other methods of testing/configuring. Your serial line speeds/bits/parity/etc., all need to match the device you're hooking to...which you ALSO haven't told us about.


Very; especially since that has been deprecated for a while now. Don't even have an /etc/rc.d directory on my system, nor an rc.local. While it MAY exist on some systems still, we don't know unless the OP actually provides details.

As noted, installing this mystery card is probably pointless, since the USB to serial device will more than likely function just fine...I have never had an issue with one.

^ Firasalrawi, please answer ALL these questions.

Probably because you don't have permission.
You need to edit & save the file with elevated privileges (e.g. sudo...).
BTW, depending on your distro, these instructions might be outdated anyhow.

AFAIK there is no LINUX device manager that will display a device that way. This comment appears to be based on the windows display of devices and does not in any way affect what is seen in Linux.

You cannot ever use what is seen in windows as indicative of how Linux manages and configures devices.

Please consider answering the questions asked and provide useful information if you wish assistance here.
