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...

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.

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!

A:Serial Port Help

If the plug has a pic of a monitor on it, the socket is probably for the onboard Video. I'm guessing that you are not in the right area for the serial ports?

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 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.

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

At work I was using a laptop with a serial port, which I used to communicate with an electronic device. The application used for the communication between the laptop and the device is designed to use a serial port.
The problem is I have now got a new laptop without a serial port (this seems to be the thing now!?) and I'm trying to use the USB port instead. My laptop doesn't like this at all!
Is there any way to configure the laptop to make the application think that it is talking to a serial port when it is in fact connected to the USB?
Any pointers anyone?

Hello. I have a digital camera that must use a serial port. I can not get the comp. to recognize the camera. The software that came with the camera has been successfully installed (or so I'm told). I have two serial ports, one is 9 pin the other is larger.The camera requires the 9 pin connection. The 9 pin is on Com 1 and has the settings IRQ:4 Range:03F8-03FF. I am using a cable modem, and I do not have a dial up modem installed. I have checked the device manager and there are no exclaimation points or "X's" by Com 1. Device manager also reports no conflicts with Com 1. Any suggestions for resolving this problem would be appreciated.

I am planning on buying an MSI P67A-GD55 (B3) motherboard and I noticed it has a serial port header onboard. I would like to know where I wan buy an adapter to utilise this header. I searched it up and found this: http://www.cablestogo.com/product.asp?cat_id=3543&sku=28300
But that is just for Intel motherboards. Does anyone know where I can get one for my motherboard?

A:Solved: Where to buy serial port?

That adaptor should work fine on that board as far as I can tell. When it says its for Intel boards it is refering to the motherboard chipset not the manufacturer. The MSI board you have listed has a serial port connector and they are standard as far as I am aware. However, I haven't used or needed a serial port for many years so I am not overly familiar with them.

I'm running as ASUS A7V600 motherboard, WIN XP Home edition. Two on-board serial ports, Award V6.0 BIOS. I have four serial ports, the second two being on a Lava DSerial PCI card. The serial ports are necessary in order to interface with some equipment that pre-dates USB. The application software that's used has a sensitivity to the I/O address (not the COM port number), and will work properly only when the I/O address is that which is normally associated with a given com port number.

So, the software works just fine with the two onboard ports since they have the addresses 03F8 and 02F8. However, the Lava port addresses on com 3 and com4 are set to FFE8 and FFF8. Win XP home allows you to change the com port number OK, but doesn't allow you to change the I/O address range used as previous OSs did. Lava tech support says the addresses are assigned by the BIOS and there's nothing they can do.

There must be some way to influence the BIOS into assigning other I/O addresses (03E8 and 02E8 would be nice!), but haven't had any luck with that. Is there some way I can force this to come out the way I want?

A:Serial port I/O addresses


Does the A7V MB have any ISO slots? If it does you can use a ISO COM card from
a site that I buy parts from:


If it does not have any ISO slots? You can still check with cyberguys to see if they have a addressable PCI COM card.

I have peripherals that attach via USB/serial cable. Each time I plug into a USB port, apparently XP is assigning another Com # to it. The peripheral software can only be configured up to Com10. The only USB ports in constant use are printer, mouse, and scanner. These are always connected. I can go into the device manager to access the ports and try to reassign a lower com # but the port is being reported as "in use" rendering it unavailable for anything. How do I clean these out or reset com #'s ? or stop the enumeration process ?
I have, in safe mode, tried to remove all USB ports, hub controllers and serial ports for the pc. I have also removed all instances of the drivers for the serial/usb ports as well as the software requiring it use. Upon restarting, all ports are reinstalled including the phantom ones. XP insists on remembering.......
Thanks in advance for any guidance here.......

Whenever I run our serial test, it fails the handshake portion of the test consistently. I have other serial testers, and they work fine, but I need this one to work properly. Is the loopback pinned out differently, or can I jump some of the connections to make it work? Any help is appreciated!

Are you trying to loopback test on the same connector or between two different connectors? You may have a loopback adapter/tester for testing between one serial port with a 9 pin plug and one with a 25 pin plug. I found a description of such a cable in some Sun Microsystems documentation here:


That same documentation has information on wiring 9 pin and 25 pin plugs for loopback testing on the same port.
