Usb Serial Port Adapter

Q: Usb Serial Port Adapter

i have a usb serial port adapter and i trying to figure out to set the usb jack on the desk top to be port1, port2, port3, or port4. if this is an easier process with xp i can change to the laptop

Preferred Solution: Usb Serial Port Adapter

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A:USB to serial port adapter not working on Windows 8

Welcome to Tech Support Guy

What is the serial device you are trying to connect
What is the make of the USB to serial adapter

The problem is that the processor chip - YES they do have one, is not in many cases compatible with Windows 8, especially 64 bit, as of course the actual working of the adapter is achieved by connection to the USB port and then transmission of data from and to the USB hub.

Not knowing what you actually wish to connect your best first port of call is here to see what is on offer

scroll down for USB to serial or click USB on menu at top

My PC doesnt have a parallel port. My printer is not USB-capable. So, I connected an adapter (9-pin plug in one end/25-pin plug other end) to the 9-pin serial port of the PC and plugged the printer cable in the adapter. On connecting, the PC communicated w/the printer because a paper came out with a single black square on top. But I could not get it to print again. I tried printing directly from CMD prompt to LPT1; then tried COM1 and COM2 - No luck. Any suggestions? The printer is a discontinued HP Laserjet 4000 - it may have a serial port, in which case I may go from serial to serial but, is that okay? Thanks for your help.

Need some advice a quick as possible.

Windows XP Pro
ofc had a built in serial port go bad, it was hooked to a charicter generator (don't no how to spell charicter) for a tv channel.
Installed a Controller Card with two serail ports PCI Multi I/O Controller Card, it didn't show up in the device manager was having problems getting the driver to work. says to load driver first then put in the pci card. Anyway it wouldn't work. The port that was built in (that went bad was on com 1) When the new card didn't work I used a usb with a serial adaptor and it went in fine and showed up in the divice manager and it said it was working and it started out on com 3, I no each time you plug the adaptor into a different usb port it goes to a different com port. That isn't a problem cause it would stay in the same port. Anyway device manager said it was working we changed the charicter generator to com 3 but it wouldn't work. We no the cables are good. I then got a PCI Card with one serial port instead of two and installed it and it show right up in the device manager and said it was working and I for get what comport it was on but changed it to com 1. that port didn't work either. Finally brought in another windows xp computer and hooked everhthing to it and it works. The xp computer I brought in had no serial port so used the same usb to serial adaptor that we had used and it work the first time. Show up in the device manager just like on the first comp...

On an Acer travelmate 518TX serial port I feed signals coming from a DSP. The signal is processed by a charting software that builds up the page line by line.
Happens that the image makes, at regular intervals a small jump to the left. So doing the final page is make up in stripes.
The software manufacturer states that some othe program is interrupting the incoming data stream from serial port, suggesting to disabling the Power Management System. I did it without any result.
My question is:
Can someone address me to what could be devices or software that commonly sample the serial port ? In order to investigate on how to stop this chopping activity.

I need to turn on my serial port and I don't know how to access the controls in the BIOS...
I have a Compaq Presario 5108US desktop. I have disabled the Windows XP "welcome screen" during reboot so that now I see the commands when my computer boots up. I don't know the proper keys to push to allow me to access the BIOS controls.

Can anyone help?

A:Serial port

Sorry I didn't get back to you on the other post, been crazy around here...

Anyway, press F10 repeatedly when your computer boots up to enter the BIOS. After you reach the BIOS main menu, see if you can find a menu or setting for Serial Port. It is probably under the menu, Integrated Peripherals, or a menu similar to that. There should be an "Enable/Disable" option.

Let me know if this works for you

Hi - I am selling a sewing machine that has a serial port on the side but most people use USB sticks these days to transfer embroidery designs into their machines. The convertors I have seen have a male connection whereas I need a female connection. Does anyone know if there is a convertor that has a female connection? Thanks!

A:Help with serial to USB port

Hi judysue2, and welcome to TSG.

Are you talking about the USB connector or the 9 pin D-sub serial connector?

There are 9 pin serial cables that come in all combinations of male and female connectors on each end. There are also 9 pin D-sub "gender changer" blocks available.

EDIT: The serial port on your sewing machine is most likely designed to connect to a computer running specific downloading software for the machine. A general purpose serial-to-USB adapter would not have the built-in software needed to read the memory stick and send the data to the machine.

I am trying to connect my fiancee's palm pilot via serial port to my computer running windows XP. I have tried both serial ports on the back of my computer (one has a picture of a monitor and one has a picture of what reminds me of a lego Oh, and these are 9-pin ports I believe). Anyway, I can't get the palm pilot to sync with the computer. After looking at the FAQ section on Palm's website, it sounds like the reason it isn't working is because of conflicting COM/IRQ addresses.

Can someone please tell me the best way to see if there are any COM ports available on my computer and, if there's not, how to free one up? Thanks in advance!

So im going to try to explain this as well as i can.
I am running a windows 7 and I have a radio I would like to program. The main issue is that the program needed to program it is for DOS. So I installed DOS 6.22 On my VMWare virtual machine (VMware Workstation 8.0.0) and ran the program. Now the radio connects with a serial cable. but since I am using my laptop (lenovo ideapad z575) It does not have a Serial port. So I am using a USB to Serial Adapter (Trendnet TU-S9). But DOS will not recognize it.

What I am wanting to do overall is to make my windows 7 computer assume that my USB adapter is a physical Serial port so that I can go into VMware and attach a "physical" serial port to my VM. any Ideas or other suggestion i could try? thanks and sorry for the read.

A:USB serial port help

Did the trendnet USB to serial adapter come with drivers? Usually devices like that will. If not you can find them on the website most of the times. You may have to just install the drivers on your machine, and within the VM.

When I rebuild them (Win10 Pro/64-bit) , I frequently have a "PCI Serial Port" error remaining in Device Manager even though I've installed the latest drivers for that model. Quite often I can't get rid of the error, and so I have to place a faulty machine into service.    What's the cause of this error, and how do I correct it?

Thats OK, because these aren't intergrated, and you don't have intergrated peripherals.

"com3 and4 were auto assigned"
Don't quite understand, but I think thats good.

Try another PCI slot. XP should automatically detect the card and automatically assign the correct resources(unless it needs drivers) and they should appear in Device Manager. Is there anything in Device Manager that has an error?

have a HD tuner card that uses the serial port for the IR receiver. It places a icon in the system tray and that is where the infomation for any timed recording is held. I manually put the system into hibernation and 2 minutes before the recording is scheduled to begin the system wakes up (comes out of hibernation) and the program loads and the recording starts. After the recording the program closes and it shuts down the system (or what ever optiuon you choose).

Problem is it's NOT bringing the system out of hibernation any more. It did orginally, but not now. To make a long story shorter, the problem seems to be in the serial port and/or the TCP/IP portion of it since that is how the communicatiuon is handled so I'm told by the vendor of the card. I tried two other programs that will bring the system out of hibernation and the system does respond.

I tried:

changing Bios versions
reloading the O/S
reloading the program
removing cards

A:Serial Port Problems!

I don't know about cameras, but let's see if it is a COM port problem.

Did you try both serial ports?

Are both serial ports recognized by WIN95? Open Control Panel and click on System.
Left click on the Device Manager tab and scroll down to "Ports (COM & LPT).
Double click.
Are there serial ports listed there?
Any exclamation points?

If one or no ports are listed you will first have to turn them on in your system BIOS. I have mine turned off to free up some IRQs.

You will find them in the BIOS usually on the page called "Integrated Peripherals".
Always write down your bios settings so that you can restore them if neccessary!

If you have both COM ports, and it still doesn't work, hopefully someone who knows a little more can help you further.

Good luck.

I'm trying to use a serial port on my PC, the GB board (H97-D3H) has a COM port header and I've used a back panel connector with cable to connect to this. I checked and serial port in enabled in BIOS. The driver is the Microsoft driver serial.sys and claims it is working. I believe the support for the COM header connection is through the chipset. I've downloaded and installed all the latest drivers from Gigabyte. I'm trying to connect to a device to update firmware and connection is via serial connection.

Any suggestions for troubleshooting? Would I need a specific driver that supports the chipset to run this serial port? Lots of USB-serial and virtual serial port drivers found by googling but can't find another driver for Win7 x64 to try. Any other suggestions on how to get the device to connect?
