This document and the gadget serial driver itself areCopyright (C) 2004 by Al Borchers (alborchers@steinerpoint.com).
If you have questions, problems, or suggestions for this driverplease contact Al Borchers at alborchers@steinerpoint.com.
Prerequisites¶
Versions of the gadget serial driver are available for the2.4 Linux kernels, but this document assumes you are usingversion 2.3 or later of the gadget serial driver in a 2.6Linux kernel.
This document assumes that you are familiar with Linux andWindows and know how to configure and build Linux kernels, runstandard utilities, use minicom and HyperTerminal, and work withUSB and serial devices. It also assumes you configure the Linuxgadget and usb drivers as modules.
With version 2.3 of the driver, major and minor device nodes areno longer statically defined. Your Linux based system should mountsysfs in /sys, and use “mdev” (in Busybox) or “udev” to make the/dev nodes matching the sysfs /sys/class/tty files.
Overview¶
The gadget serial driver is a Linux USB gadget driver, a USB deviceside driver. It runs on a Linux system that has USB device sidehardware; for example, a PDA, an embedded Linux system, or a PCwith a USB development card.
The gadget serial driver talks over USB to either a CDC ACM driveror a generic USB serial driver running on a host PC:
On the device-side Linux system, the gadget serial driver lookslike a serial device.
On the host-side system, the gadget serial device looks like aCDC ACM compliant class device or a simple vendor specific devicewith bulk in and bulk out endpoints, and it is treated similarlyto other serial devices.
The host side driver can potentially be any ACM compliant driveror any driver that can talk to a device with a simple bulk in/outinterface. Gadget serial has been tested with the Linux ACM driver,the Windows usbser.sys ACM driver, and the Linux USB generic serialdriver.
With the gadget serial driver and the host side ACM or genericserial driver running, you should be able to communicate betweenthe host and the gadget side systems as if they were connected by aserial cable.
The gadget serial driver only provides simple unreliable datacommunication. It does not yet handle flow control or many otherfeatures of normal serial devices.
Installing the Gadget Serial Driver¶
To use the gadget serial driver you must configure the Linux gadgetside kernel for “Support for USB Gadgets”, for a “USB PeripheralController” (for example, net2280), and for the “Serial Gadget”driver. All this are listed under “USB Gadget Support” whenconfiguring the kernel. Then rebuild and install the kernel ormodules.
Then you must load the gadget serial driver. To load it as anACM device (recommended for interoperability), do this:
To load it as a vendor specific bulk in/out device, do this:
This will also automatically load the underlying gadget peripheralcontroller driver. This must be done each time you reboot the gadgetside Linux system. You can add this to the start up scripts, ifdesired.
Your system should use mdev (from busybox) or udev to make thedevice nodes. After this gadget driver has been set up you shouldthen see a /dev/ttyGS0 node:
Note that the major number (253, above) is system-specific. Ifyou need to create /dev nodes by hand, the right numbers to usewill be in the /sys/class/tty/ttyGS0/dev file.
When you link this gadget driver early, perhaps even statically,you may want to set up an /etc/inittab entry to run “getty” on it.The /dev/ttyGS0 line should work like most any other serial port.
If gadget serial is loaded as an ACM device you will want to useeither the Windows or Linux ACM driver on the host side. If gadgetserial is loaded as a bulk in/out device, you will want to use theLinux generic serial driver on the host side. Follow the appropriateinstructions below to install the host side driver.
Installing the Windows Host ACM Driver¶
To use the Windows ACM driver you must have the “linux-cdc-acm.inf”file (provided along this document) which supports all recent versionsof Windows.
When the gadget serial driver is loaded and the USB device connectedto the Windows host with a USB cable, Windows should recognize thegadget serial device and ask for a driver. Tell Windows to find thedriver in the folder that contains the “linux-cdc-acm.inf” file.
For example, on Windows XP, when the gadget serial device is firstplugged in, the “Found New Hardware Wizard” starts up. Select“Install from a list or specific location (Advanced)”, then on thenext screen select “Include this location in the search” and enter thepath or browse to the folder containing the “linux-cdc-acm.inf” file.Windows will complain that the Gadget Serial driver has not passedWindows Logo testing, but select “Continue anyway” and finish thedriver installation.
On Windows XP, in the “Device Manager” (under “Control Panel”,“System”, “Hardware”) expand the “Ports (COM & LPT)” entry and youshould see “Gadget Serial” listed as the driver for one of the COMports.
To uninstall the Windows XP driver for “Gadget Serial”, right clickon the “Gadget Serial” entry in the “Device Manager” and select“Uninstall”.
Installing the Linux Host ACM Driver¶
To use the Linux ACM driver you must configure the Linux host sidekernel for “Support for Host-side USB” and for “USB Modem (CDC ACM)support”.
Once the gadget serial driver is loaded and the USB device connectedto the Linux host with a USB cable, the host system should recognizethe gadget serial device. For example, the command:
should show something like this::
If the host side Linux system is configured properly, the ACM drivershould be loaded automatically. The command “lsmod” should show the“acm” module is loaded.
Installing the Linux Host Generic USB Serial Driver¶
To use the Linux generic USB serial driver you must configure theLinux host side kernel for “Support for Host-side USB”, for “USBSerial Converter support”, and for the “USB Generic Serial Driver”.
Once the gadget serial driver is loaded and the USB device connectedto the Linux host with a USB cable, the host system should recognizethe gadget serial device. For example, the command:
should show something like this::
You must load the usbserial driver and explicitly set its parametersto configure it to recognize the gadget serial device, like this:
The legacy way is to use module parameters:
If everything is working, usbserial will print a message in thesystem log saying something like “Gadget Serial converter nowattached to ttyUSB0”.
Testing with Minicom or HyperTerminal¶
Once the gadget serial driver and the host driver are both installed,and a USB cable connects the gadget device to the host, you shouldbe able to communicate over USB between the gadget and host systems.You can use minicom or HyperTerminal to try this out.
On the gadget side run “minicom -s” to configure a new minicomsession. Under “Serial port setup” set “/dev/ttygserial” as the“Serial Device”. Set baud rate, data bits, parity, and stop bits,to 9600, 8, none, and 1–these settings mostly do not matter.Under “Modem and dialing” erase all the modem and dialing strings.
On a Linux host running the ACM driver, configure minicom similarlybut use “/dev/ttyACM0” as the “Serial Device”. (If you have otherACM devices connected, change the device name appropriately.)
On a Linux host running the USB generic serial driver, configureminicom similarly, but use “/dev/ttyUSB0” as the “Serial Device”.(If you have other USB serial devices connected, change the devicename appropriately.)
On a Windows host configure a new HyperTerminal session to use theCOM port assigned to Gadget Serial. The “Port Settings” will beset automatically when HyperTerminal connects to the gadget serialdevice, so you can leave them set to the default values–thesesettings mostly do not matter.
With minicom configured and running on the gadget side and withminicom or HyperTerminal configured and running on the host side,you should be able to send data back and forth between the gadgetside and host side systems. Anything you type on the terminalwindow on the gadget side should appear in the terminal window onthe host side and vice versa.
Television today is very important part of our daily lives in this modern world, such as 24 inch TV. World is like a global village in this era of information technology. So anything which is source of information and connects you to the world is of vital importance. Television is a great source of information and global connectivity.

- How big is the 24 inch TV
- What size of the room is good for 24 inch TV
- Commonly used resolution of 24 inch TV
- LCD panel of 24 inch TV
- Curved 24 inch TV
- Backlight of 24 inch TVs
- Power consumption of 24 inch TV
- Interface of 24 inch TV
- Conclusion
1.Smart features of 24 inch smart TV
The first thing to consider before buying a television is the smart features. The conventional television is becoming obsolete. People tend to have their television as a versatile source of entertainment where they can watch television programs, play games, browse the web or meet with their dear ones through video chat. Yes, all of this is possible in a smart TV.
Unlike conventional television, a smart television is like a mini computer where you have a storage space for installing different applications and storing pictures and videos. The size of storage should be looked up before buying a smart television.
With increased storage you can store lot of data a play it directly through television remote. Another important feature is internet connectivity. Smart TV features Wi-Fi through which you can browse internet. Having such capabilities, smart TV is an entertainment system per se.
A few 24 inch smart TV have smart features, and there are also many simple versions available. For a small TV these features are quite necessary nowadays. The 24 inch smart TV has higher price than a simpler version. A certain smart TV may not have all these features. So, you must make sure that the features you require are available in the 24 inch smart TV you are buying.
2. Where to buy the 24 inch TV
When buying a TV, the biggest question is where to buy. The most common choice is buying from local electrical appliance stores or super markets, such as the Walmart and so on. The main advantage is that you can see and check the product before buying and take it home right away. The disadvantage is that the price is higher. Products are priced higher on stores because they need to pay for rents, bills and salaries.
The easiest choice is buying from online store, such as the Amazon, eBay and so on. You can view the television specification from the comfort of your home. The price of products on online stores is cheaper but once bought you may have to wait several days to get it. It may be 15 days to 25 days.
Another downside is that the quality cannot be guaranteed. We reviewed several comments of the 24 inch TV on the online platform. Plenty of them said that there are quality problems, such as the color of the screen is too bad, or the sound is terrible and so on. You may not know that the product you are buying is refurbished or used. So, it is risky to buy from an online platform.
If you want to buy several pieces of televisions, the best choice is to buy them from the manufacturers directly. In this case, the product quality is guaranteed, and price is a lot cheaper. If the products are shipped by air, you can get them in one week.

3.How big is the 24 inch TV
Many people are confused what the mentioned screen size mean. The screen size refers to the diagonal length of the screen. The mentioned size may not be exact. Different manufacturers produce screen with slight variations. The screen size of a 24 inch TV may be 23.6-inches, 23.8-inches or exactly 24-inches.
This small difference is not noticeable. So, the commonly used display area of 24 inch TV is about 521.28 x 293.22 mm, 527.04 x 296.46 mm or 531.36 x 298.89 mm. The overall size of television is different as there is a frame around screen. So, the actual diagonal size of television is different and includes the frame as well. Many people prefer thin frame size which looks sharp and beautiful. This feature is called slim bezel.
Most of the 24 inch TVs come with adjustable stand. While placed on a table, you can adjust the height and orientation of screen. So the whole sizes are also different. In general, the approximate range of the length, height, thickness are follows: 560 to 600mm, 350 to 440mm, 65 to 90mm (without stand). Before buying a television, you should look out for all these details.
4. What size of the room is good for 24 inch TV
Many people have difficulty deciding the right size of TV for their room. There is no definite rule but watching a bigger television closely is dangerous for your eyes. Similarly, you would have difficulty watching smaller television from far and it can cause headache.
Many people have different opinion for the viewing distance. In general, experts say that the viewing distance is three times the size of television. That means the viewing distance for 24-inch television is 72 inches. So, from the size of your room you can decide which size of television you require. In general, a 24-inch TV is quite suitable for medium size rooms like bedroom etc.
5. Commonly used resolution of 24 inch TV
The screen resolution of a TV makes a great difference. Make sure you get the right resolution for your requirements. With the same size, the higher the resolution, the clearer the image quality will be.
The most frequently used resolution of 24 inch TV 1920 x 1080 which is FHD (Full High Definition) or 1080P. In recent years, the 24 inch 4K TV which the resolution is 3840 x 2160 is more and more popular. The price of 24 inch 4K television is higher but you shouldn’t mind spending some extra money when features are so attractive.
6. LCD panel of 24 inch TV
Different manufacturers use different types of panels or screen such as AUO, BOE, LG, Samsung and so on. The screen from each manufacturer is graded in different categories such as A+, A, B, C and so on.
The A+ screens having quite uniform colors and no bright and dark spots are the best and the price is also the highest. These spots are only visible through specialized software’s and make no difference in watching television. The high-quality televisions always use the screens of A or B grades.
The screen of 24-inch television has three kinds, 23.6”, 23.8” and 24”. The resolution of 23.6 inch and 24” are mostly 1920 x 1080, and the resolution of 23.8 inch can be 1920 x 1080 or 3840 x 2160. This is manufacturer and model specific parameters. The television manufacturers just can select and decide to use which one. Whole buying a 24-inch TV, you should check the screen specifications and choose the right screen size and resolution.
7. Curved 24 inch TV
Curved screen is a relatively new technology. Their benefits include reduced eye strain and better field of view. Although the 24 inch television is considered to be small screen size, the curved TV is still available. You can have a big curved screen TV in your common room while few 24 inch flat screen TV in other rooms, or you can also buy a curved 24 inch TV for your rooms.
8. Backlight of 24 inch TVs
Backlight of television refers to the illumination of LCD screen. Old television had backlight on the inner side of screen but now backlight is divided in two kinds: side illuminated and straight down.
Side illuminated backlight comes in traditional television. The side illuminated TV has the led source on the top and bottom side of television screen. It uses the edge-lit backlight technology. There are two led strips or CCFL tubes and one piece of acrylic light guide plate in LCD screen. So, the backlight on screen seems uniform.
The straight down TV backlight uses several LED strips to provide backlight directly. So, there is no need for acrylic light guide plate. For little more thickness you get the product in cheaper price. This technology has become quite popular in recent years.
Most of the 24 inch TVs in market are side illuminated and the light source is LED. Checking the backlight type is an important parameter while buying TV. If it is CCFL or screen type is LCD, the screen would be based on old technology. This technology has become obsolete in recent years.
9. Power consumption of 24 inch TV
To keep the electricity bills in check, you should look for power consumption of your electrical appliances. There are two major parts of power consumption: Power consumed by LCD screen and power consumed by controller. The power consumption of LCD screen with WLED light source is about 25W. It is the main power consumption of 24 inch TV. For the controller, it is just 0.5W in standby mode.
So according to the information, how can we calculate the cost of the electricity? If the total power consumption of a 24 inch television is 30W, we use the TV for 4 hours every day and the price of electricity is 1 dollar per KWh. So the cost of everyday is (30 x 4 / 1000) x 1 = 0.12 dollar. So, its power consumption is very low. The older tube technology television consumes a lot of power, putting a strain on electricity bill.
10. Interface of 24 inch TV
Drivers.com Gadget Serial Com 244) Watch
Another important thing to look out for is the types of interfaces the TV has. There are several interfaces for 24-inch television such as RF-in, AV-in, HDMI, VGA, USB and so on. You should look carefully for the available features before buying the television. Following is the description of each of these interfaces:
(1).HDMI:High Definition Multimedia Interface (HDMI) is digital audio and video transmission interface used in modern devices. This is the most common interface that most devices support. This port can be used to connect DVD, set-top box, personal computer, gaming console etc. Having this interface is must even if you do not have any HDMI device currently. You may buy a new product having HDMI interface.
Gadget Serial V2.4
It is quite useful for small room in home where you can connect DVD, set-top box and computer at the same time on different HDMI ports of your television and switch the signal source through remote. This makes your television multipurpose and you can easily switch from entertainment to office work etc.
(2).VGA:Video Graphics Array (VGA) is analogue video transmission interface. It has similar features as HDMI port, but this interface is becoming obsolete. So why have both? This feature is added for universal compatibility. The user may have an old device having VGA interface. So, unless your TV has this interface, you would not be able to connect the device. Variety of different devices may feature VGA or HDMI port. Having both will give you an option to choose one.
(3).USB:Universal Serial Bus (USB) is the most common and perhaps the most important device connection interface. Most TV feature a USB port through which you can connect pen drives and storage drives and play the videos directly from it. This provides a freedom of choice.
What if your favorite movie is not available on streaming service? If you have USB interface, you can easily play the movie from USB. It is also sometimes necessary in cases where the set-top box is not ready or malfunctioning. So, USB becomes an easy and useful alternative.
(4).AV-in:It is the audio-video input interface. It is used to connect DVD, DTV etc. Although this technology is a bit old, but it is still in use.
(5).RF-in:This is the interface for connecting antenna. This interface was used widely when there were no digital streaming services. This interface is now obsolete.
11.Conclusion
24 inch TV is quite suitable for medium sized rooms. Helping you buy the right TV is our top-most priority. Having a detailed knowledge of features mentioned above can help you a lot in choosing the right product and getting the best quality in minimum price.

So what are the benefits of using a 24 inch TV?
Drivers.com Gadget Serial Com 244) Serial
(1). Low power consumption. In many homes, a TV will be on throughout the day, making it one of the contributors to high power bills. Like any other gadget, TVs will also consume power depending on the size.
Having a larger screen means higher power bills, and if you want to cut the costs, you need to consider the size of the TV you use. A 24 inch flat screen TV will consume less power making it your best choice. No matter how many hours you watch your TV; you will not pay exaggerated power bills.
(2). Suitable for small rooms. Having a TV in the bedroom or kitchen is a common thing in many houses. As you cook, you may want to watch your best TV show. But you need to be conscious of the type of TV you will use in your kitchen or bedroom.
Using a large TV will congest your small room, and even harm your eyes. When you are watching TV at a close distance, you need one with a small screen so that there will be less light. A 24 inch led TV will give the best service when it comes to small rooms.
(3). Pocket-friendly. Although the price of a TV will depend on the model and quality, size is another significant factor. A large low-quality TV will always be more expensive than a small high-quality one. For example, a 65 inch digital TV will always be costly than a 24 inch smart TV.
If you want to get a quality TV without digging deep into your pocket, then a 24-inch size might be your choice. With little cash, you can even get a 24 inch full HD TV which will never be possible with larger sizes.
(4). Flexible. Another good thing with a 24 inch TV is that its flexible and you can place it anywhere in your room. With a large TV, it will be hard to rearrange your room, and if you love changing the arrangements after every few months, this is the right TV to keep. No matter the arrangement plans a small TV will always fit.
Although there are large TVs in the market, small sizes will also be helpful. A 24 inch TV comes with several advantages making it the choice to many people. However, you need to ensure you get a good model that will last.
