Usb serial number linux

[Step-by-Step] How to get serial number in Linux (Ubuntu) by Command?

For Windows: If you are using Windows, you can check serial number and all other hardware related information in system property using User Interface. You can also get system info using system information command in windows.

For Linux: If you are using any of the Linux systems, you have to run the command to the system details like serial number, manufacturing model… You can do this easily by the dmidecode command in the command line terminal.

What is the dmidecode command?

It is a command to read DMI table. The name itself depicts as it is a command to decode the value in DMI table.

What is DMI Table in Linux?

DMI table is also called as SMBIO. This table consists of all the hardware, processor, system, BIOS information, etc.

Role of dmidecode Command:

A dmidecode command just fetches the content from this table and display it in the human-readable format on the terminal.

Run this command.

If it is not working, it requires root permission. Try getting admin privilege by running following sudo command.

It will give a long list of information. To shorten it or to get the particular information you have to be specific.

How to check the Manufacturer, Model, and Serial Number?

Run the following command.

This command will give complete information about the system.

How to get serial number in Linux?

If you want to get a serial number of the system in any Linux system like Ubuntu, run following command in terminal.

This will highlight the serial number of the hardware.

You can also use the dmidecode to read any specific hardware/system parameter by specifying the parameter name.

Note: Kindly make a note. While running any of the dmidecode commands, try all these commands running without sudo first. If you get any error or system ask you for any privilege, use the commands with sudo.

I have tested and verified all these commands on Ubuntu Linux machine. If you are using any other Linux OS system, kindly check, How to get serial number in Linux using the same commands. Do share your result. It will be helpful for other candidates.

USB serial¶

Introduction¶

The USB serial driver currently supports a number of different USB to serial converter products, as well as some devices that use a serial interface from userspace to talk to the device.

See the individual product section below for specific information about the different devices.

Configuration¶

Currently the driver can handle up to 256 different serial interfaces at one time.

The major number that the driver uses is 188 so to use the driver, create the following nodes:

When the device is connected and recognized by the driver, the driver will print to the system log, which node(s) the device has been bound to.

Specific Devices Supported¶

ConnectTech WhiteHEAT 4 port converter¶

ConnectTech has been very forthcoming with information about their device, including providing a unit to test with.

The driver is officially supported by Connect Tech Inc. http://www.connecttech.com

For any questions or problems with this driver, please contact Connect Tech’s Support Department at support @ connecttech . com

HandSpring Visor, Palm USB, and Clié USB driver¶

This driver works with all HandSpring USB, Palm USB, and Sony CliГ© USB devices.

Only when the device tries to connect to the host, will the device show up to the host as a valid USB device. When this happens, the device is properly enumerated, assigned a port, and then communication _should_ be possible. The driver cleans up properly when the device is removed, or the connection is canceled on the device.

This means that in order to talk to the device, the sync button must be pressed BEFORE trying to get any program to communicate to the device. This goes against the current documentation for pilot-xfer and other packages, but is the only way that it will work due to the hardware in the device.

When the device is connected, try talking to it on the second port (this is usually /dev/ttyUSB1 if you do not have any other usb-serial devices in the system.) The system log should tell you which port is the port to use for the HotSync transfer. The “Generic” port can be used for other device communication, such as a PPP link.

For some Sony CliГ© devices, /dev/ttyUSB0 must be used to talk to the device. This is true for all OS version 3.5 devices, and most devices that have had a flash upgrade to a newer version of the OS. See the kernel system log for information on which is the correct port to use.

If after pressing the sync button, nothing shows up in the system log, try resetting the device, first a hot reset, and then a cold reset if necessary. Some devices need this before they can talk to the USB port properly.

Devices that are not compiled into the kernel can be specified with module parameters. e.g. modprobe visor vendor=0x54c product=0x66

There is a webpage and mailing lists for this portion of the driver at: http://sourceforge.net/projects/usbvisor/

For any questions or problems with this driver, please contact Greg Kroah-Hartman at greg @ kroah . com

PocketPC PDA Driver¶

This driver can be used to connect to Compaq iPAQ, HP Jornada, Casio EM500 and other PDAs running Windows CE 3.0 or PocketPC 2002 using a USB cable/cradle. Most devices supported by ActiveSync are supported out of the box. For others, please use module parameters to specify the product and vendor id. e.g. modprobe ipaq vendor=0x3f0 product=0x1125

The driver presents a serial interface (usually on /dev/ttyUSB0) over which one may run ppp and establish a TCP/IP link to the PDA. Once this is done, you can transfer files, backup, download email etc. The most significant advantage of using USB is speed — I can get 73 to 113 kbytes/sec for download/upload to my iPAQ.

This driver is only one of a set of components required to utilize the USB connection. Please visit http://synce.sourceforge.net which contains the necessary packages and a simple step-by-step howto.

Once connected, you can use Win CE programs like ftpView, Pocket Outlook from the PDA and xcerdisp, synce utilities from the Linux side.

To use Pocket IE, follow the instructions given at http://www.tekguru.co.uk/EM500/usbtonet.htm to achieve the same thing on Win98. Omit the proxy server part; Linux is quite capable of forwarding packets unlike Win98. Another modification is required at least for the iPAQ — disable autosync by going to the Start/Settings/Connections menu and unchecking the “Automatically synchronize …” box. Go to Start/Programs/Connections, connect the cable and select “usbdial” (or whatever you named your new USB connection). You should finally wind up with a “Connected to usbdial” window with status shown as connected. Now start up PIE and browse away.

If it doesn’t work for some reason, load both the usbserial and ipaq module with the module parameter “debug” set to 1 and examine the system log. You can also try soft-resetting your PDA before attempting a connection.

Other functionality may be possible depending on your PDA. According to Wes Cilldhaire @ hotmail . com>, with the Toshiba E570, …if you boot into the bootloader (hold down the power when hitting the reset button, continuing to hold onto the power until the bootloader screen is displayed), then put it in the cradle with the ipaq driver loaded, open a terminal on /dev/ttyUSB0, it gives you a “USB Reflash” terminal, which can be used to flash the ROM, as well as the microP code.. so much for needing Toshiba’s $350 serial cable for flashing!! 😀 NOTE: This has NOT been tested. Use at your own risk.

Keyspan PDA Serial Adapter¶

Single port DB-9 serial adapter, pushed as a PDA adapter for iMacs (mostly sold in Macintosh catalogs, comes in a translucent white/green dongle). Fairly simple device. Firmware is homebrew. This driver also works for the Xircom/Entrega single port serial adapter.

basic input/output (tested with ‘cu’)

blocking write when serial line can’t keep up

changing baud rates (up to 115200)

getting/setting modem control pins (TIOCM)

sending break (although duration looks suspect)

device strings (as logged by kernel) have trailing binary garbage

device ID isn’t right, might collide with other Keyspan products

changing baud rates ought to flush tx/rx to avoid mangled half characters

parity, 7 vs 8 bits per char, 1 or 2 stop bits

HW flow control

not all of the standard USB descriptors are handled: Get_Status, Set_Feature, O_NONBLOCK, select()

For any questions or problems with this driver, please contact Brian Warner at warner @ lothar . com

Keyspan USA-series Serial Adapters¶

Single, Dual and Quad port adapters — driver uses Keyspan supplied firmware and is being developed with their support.

The USA-18X, USA-28X, USA-19, USA-19W and USA-49W are supported and have been pretty thoroughly tested at various baud rates with 8-N-1 character settings. Other character lengths and parity setups are presently untested.

The USA-28 isn’t yet supported though doing so should be pretty straightforward. Contact the maintainer if you require this functionality.

More information is available at:

For any questions or problems with this driver, please contact Hugh Blemings at hugh @ misc . nu

FTDI Single Port Serial Driver¶

This is a single port DB-25 serial adapter.

Devices supported include:

TripNav TN-200 USB GPS

Navis Engineering Bureau CH-4711 USB GPS

For any questions or problems with this driver, please contact Bill Ryder.

ZyXEL omni.net lcd plus ISDN TA¶

This is an ISDN TA. Please report both successes and troubles to azummo @ towertech . it

Cypress M8 CY4601 Family Serial Driver¶

This driver was in most part developed by Neil “koyama” Whelchel. It has been improved since that previous form to support dynamic serial line settings and improved line handling. The driver is for the most part stable and has been tested on an smp machine. (dual p2)

Chipsets supported under CY4601 family:

CY7C63723, CY7C63742, CY7C63743, CY7C64013

DeLorme’s USB Earthmate GPS (SiRF Star II lp arch)

Cypress HID->COM RS232 adapter

Cypress Semiconductor claims no affiliation with the hid->com device.

Most devices using chipsets under the CY4601 family should work with the driver. As long as they stay true to the CY4601 usbserial specification.

The Earthmate starts out at 4800 8N1 by default… the driver will upon start init to this setting. usbserial core provides the rest of the termios settings, along with some custom termios so that the output is in proper format and parsable.

The device can be put into sirf mode by issuing NMEA command:

As far as I can tell it supports pretty much every sirf command as documented online available with firmware 2.31, with some unknown message ids.

The hid->com adapter can run at a maximum baud of 115200bps. Please note that the device has trouble or is incapable of raising line voltage properly. It will be fine with null modem links, as long as you do not try to link two together without hacking the adapter to set the line high.

The driver is smp safe. Performance with the driver is rather low when using it for transferring files. This is being worked on, but I would be willing to accept patches. An urb queue or packet buffer would likely fit the bill here.

If you have any questions, problems, patches, feature requests, etc. you can contact me here via email:

(your problems/patches can alternately be submitted to usb-devel)

How To Check and Use Serial Ports Under Linux

Display Detected System’s Serial Support Under Linux

Simple run the dmesg command:
$ dmesg | grep tty

A note about USB based serial ports

USB to RS232 adapter cable connects from the USB port of a computer to a device. Such serial to USB adapter connects to devices for configuration or programming under Linux. Here is what the dmesg command displays when you enter USB adapter:
$ dmesg
## use grep command/egrep command to filter out USB devices ##
$ dmesg | grep -i serial
$ dmesg | grep -i FTDI

Listing and using USB serial ports on Linux

Here is how it looks when I attached USB device:
$ sudo dmesg | more

Use the setserial command to check and use serial ports

The setserial is a program designed to set and/or report the configuration information associated with a serial port. This information includes what I/O port and IRQ a particular serial port is using, and whether or not the break key should be interpreted as the Secure Attention Key, and so on.

Debian/Ubuntu Linux install setserial using the apt-get command/apt command

$ sudo apt install setserial

CentOS/RHEL/Oracle Linux install setserial using the yum command

$ sudo yum install setserial
Fedora Linux user try the dnf command:
$ sudo dnf install setserial

Using setserial to list serial ports and devices

Now we installed required package. Open the termial and then type the following setserial command:
$ setserial -g /dev/ttyS[0123]
If you get an error/warning that reads as “Permission denied,” try running the command as the root user. For example, I am running it using the sudo command/su command:
$ sudo setserial -g /dev/ttyS[0123]

The setserial with -g option help to find out what physical serial ports your Linux box has.

Listing or displaying USB serial ports on Linux

Try:
$ sudo setserial -g /dev/ttyUSB[01]

Linux serial console programs

Once serial ports identified you can configure Linux box and use serial ports using various utilities:

1. minicom– The best friendly serial communication program for controlling modems and connecting to dump devices
2. wvidial or other GUI dial up networking program – a PPP dialer with built-in intelligence.
3. Screen Command: Set Baud Rate [ Terminal Communication ]
4. getty / agetty – agetty opens a tty port, prompts for a login name and invokes the /bin/login command.
5. grub / lilo configuration – To configure serial port as the system console

I don’t know if this is the place, but I’m looking for information that is similar. I have 2 machines setup through a null modem. I want to read through the com port from one machine to the other. The sending machine is running Windows sending through COM1: and the receiving computer is Linux Red Hat. Any help on this would be appreciated.

You can use pyserial ,its a python package,can be used to read and write in serial ports

another simple serial console program not mentioned is gtkterm.

I want to advise you that probably there is an error in the last sentence “seserial with -g option help to find out what physical serial ports your Linux box has.”; isn’t it setserial?

I have 4 standard serial ports defined, /dev/ttyS0-4, but I added a PCI-E 16 port serial adapter, and I have not found a way to connect anything to the upper 16 ports.
How do you create the virtual links? what options do you give setserial to define the new ports?

it dosn’t work 🙁 I can’t connect to my ASA using debian.

Daemon is a program called getty used by UNIX/Linux systems. There are many different versions of getty. The first modem detected is /dev/ttys0 or /dev/ttys1. To create a link to the devices file so that you can view modem information. Type ln -s /dev/ttys1 /dev/modem.
It is essential to set the modem to AUTO ANSWER using getty.

download minicom from alioth.debian.org/projects/minicom.

create a modem config file by entering minicom -s from the root command line
select the options you want to configure using AT commands
connect to the modem by typing in minicom

Thanks very useful..save my time 🙂

Hi,everybody
I have a serial PCI card with two ports but neither of them is working, on Linux fedora 16. I have tried using “gtkterm” and “minicom” but unfortunately I can’t make a serial connection to my Cisco lab. Here is my output when I issue the command: “setserial -g /dev/ttyS[0123]”.

/dev/ttyS0, UART: 16550A, Port: 0xec00, IRQ: 16
/dev/ttyS1, UART: 16550A, Port: 0xe880, IRQ: 16
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

also I want to mention that when I try to connet throught the terminal it generates a message like so: ” Cannot open /dev/ttyS0: Permission denied”.
any help please.
abdel

Check the permissions on /dev/ttyS0… Likely problem is it’s owned by root, and is part of the uucp group. Add yourself to the uucp group, and all should be better. I’m curious to know if this is enough for you as I am having problems communicating with a serial port on Linux as well. I got past the permissions stuff, but it is still not working.

Thanks Tom,
I actually I tried but it’s does not work, still says “permission denied”. I would appreciate if you explain to me step by step the procedure how to do it, I’m knew to Linux.
Best Regards
Abdel

1) ls -la /dev/ttyS0 — This will report the permissions on the port. Typically, this will say crw-rw—- 1 root uucp. The “c” in the string indicates that it’s a “character device” the first “rw” indicates that the owner has read/write permission. The second “rw” means that the group has read/write permissions. The “—” indicates that the rest of the world has no permissions. After the “—-“, “root” indicates that the owner of the device is root, and that the group id is “uucp”. So, you either need to be root, or a member of the uucp group to have read/write access to the port.

2) To add yourself to the uucp group (to get read/write access), you need to edit the file /etc/group, and add your user name to the line that begins with “uucp:” User names are separated by commas, so add a comma, then your user name to the end of the line. You will need root permissions to edit this file.

3) log out, and log back in because group associations are made at login time, and are not queried on each request.

Thanks Tom,
here is my output from the group file I have added my username to it but does not work.

I will just give up.Thanks a lot for your help I relay appreciate it.

Your entry in /etc/group is incorrect. If you read my previous post, I said to add your user id to the line that _begins_ with uucp. You added uucp to the group of users that can access your account. You want an entry in the /etc/group file that looks something like:

The critical element is that it’s the line that begins with uucp

It works. I just add my username to ” dialout ” and it worked fine. Iwould like to thank you for you time and support.

Best Regards
Abdel

hi,
I have connected the SIM300(gsm model) to my pc running ubuntu. I need a code to send a AT command to the GSM module and it should read and display the reply.
Please let me know steps.
I tried so many methods and codes, but no use…

i need C code(program).

all my ttyS* shows unknown, earlier it was working fine, now it doesnt recognise

#cat /etc/redhat-release
CentOS Linux release 6.0 (Final)

#dmesg | grep tty

can u pls help me

tried spending time in google two days, still no success, tried connecting a brand new device too, still no success.

Sorry, but that second sentence is not necessarily true. I have a PC with two dual com port adapters. Windows sees them as COM1 -> COM4 (there is no built in COM port). Linux sees them as /dev/ttyS4->/dev/ttyS7.

/dev/ttyS0-/devttyS3 are apparently reserved, exist whether or not a physical port exists, and /dev/ttyS0 for certain is “special” in that it is used by the default terminal window:

I think minicom still superior to other console utility.

Hi All tried all of the above and still get permission denied . HELP
Kevin

/bpq$ setserial -g /dev/ttyS[012345657

/bpq$ setserial -g /dev/ttyS[012345657]

Hiiiiiiiii
Please help me
i am install minicom and use serial modem sim300 v7.03 but there is problem to type AT cmd on minicom console…….

Edgeports are very easy to use the firmware is on Ubuntu they are from 2 ports to 16+ I bought my last two of them on ebay.
