Com Port numbers

Q: Com Port numbers

I have some old hardware with an RS232 (9 pin) connection to my notebook. I have downloaded a driver for the Serial to USB converter, and my Vista Enterprise OS seems happy with it. However, the hardware only allows communication with COM ports 1 to 4, and as far as I can judge my USB ports are 8, 9 and 10. Can I renumber these ports to make communication possible, or is there another way of doing this?

A: Com Port numbers

What is the old hardware you are using?
What is the driver you downloaded?

I have found a program that may be able to help but I have never used it.
Advanced COM Port Redirector - Redirect all data sent from one serial port to any other serial port with Advanced COM Port Redirector.
As with all shareware be careful and read the licence before installing.

This was asked before by KlausdB:

"I have 4 x HDDs on SATA AHCI (Intel Controller) in Native Mode and 1 x ESATA on Win 7 Pro X64.
I noted that looking in Admin. Tools\Computer Management\Storage (as an example) the 1st HDD (Port 0 in the AHCI BIOS) is showing as "Disk 2" instead of my expectation of

"Disk 1".
Selecting the Drive's Properties correctly shows the "Location 0 (Channel 0, Target 0, Lun 0)".
I also note that the Disk Number allocation in Windows will change randomly after some reboots/startups - going anywhere from "Disk 1" to "Disk 4".  I can force/replicate this

behaviour by removing the ESATA drive.
Is this expected behaviour?
It doesn't appear to create any operating issues at this stage, however, is there a way I can force the Drive to always map to (eg) Device 0 --> Disk 1, Device 1 --> Disk 2,


 This was answered by Nicholas Li:

"As far as I know, how the disk is plugged physically and the order it is displayed are not related. For a simple example, if a drive is plugged to SATA interface 4 and it is the only disk, it will be displayed as Disk 0. If there is no related issue about
the disk order, I think we can safely ignore this."

 Because the topic was closed I want to ask a new question here:

I have three SATA hard drives :
Main system/boot drive , WD Caviar Black 1 TB, connected to the SATA 0 port
A backup drive, identical WD Caviar Black 1 TB, connected to the SATA 1 port
Another dirve, Hitachi 1 TB, connected to the SATA 2 port
When I installed Win 7, only the main drive was connected... and it remains the only drive with active/system/boot partitions.

All three drives reporr correctly in the BIOS, and in the right order, but why is it that only one of the drive (the one on SATA port 1) has a "SATA:" prefix and the others have a "HDD:" prefix ?

Why is it that the assignment of Disk #0, 1, 2 ( as seen in Disk Maanger or DiskPart) does not seem to have nay rhyme or reason?

I would have expected:

- the hardrive connected to SATA port O, to be assigned as Disk 0
- the hardrive connected to SATA port 1, to be assigned as Disk 1
- the hardrive connected to SATA port 2, to be assigned as Disk 2

but instead, I have:

- the hardrive connected to SATA port 2, is assigned as Disk 0
- the hardrive connected to SATA port 0, is assigned as Disk 1
- the hardrive connected to SATA port 1, is assigned as Disk 2

Just curious why that is.

I am assuming there is no way to chagne this. Its not something I would dream of reinstalling Windows 7 to correct ( even if it did correct it).

Best advice, leave it alone. It may bother your (and others) sense of order but it won't affect how anything works, and no re-installing Windows won't change it.

XP has a habit of remembering which com port numbers have been used before to other devices in the past. This leads to funny situations where com port numbers that are allocated to a new device seem to be high in number (sometimes greater than 20, very often greater than 10).

Is there a registry fix to force the operating system to cancel port numbers where devices are no longer detected, thus enabling new allocations to be in a sensible range of numbers

thanks for any help

Hello all. I was talking on skype and lost internet connectivity while talking. I received the error above (Firewall Settings HTTP (port 80) HTTPS port 443 FTP port 21 error message). I am running a laptop with windows XP and IE 7 and my antivirus is AVG and I also have Ad-Aware.

I'm not much of a computer person but I did some research online and tried a few things: I turned off the option on skype's advanced settings for it to listen on Port 80 and then rebooted. I also ran a command, 'netstat -aon' and did not find a listing of 1270.0.1:80/443 or which seems to imply that nothing should be affecting port 80 or 443.

I also downloaded firefox and it cannot access the internet either. The only way I'm able to access the internet at the hotel I'm located at was to call the hotel's tech support and they had me go into the LAN settings of internet options and manually select port 8080.

Well, this has me baffled. My Bell Internet Security Services Activation (I just installed it on a computer not used for some 4 or 5 months) popped up a window saying "Waiting for Internet connection"...and waiting and waiting. But my Netgear wireless connection to the router in the house indicates "very good" signal strength, which I thought meant I was connected. Obviously not!

I tried opening IE. "Internet Explorer cannot display the web page" (much as I expected)

Clicked the button which was showing on the IE cannot connect page "Diagnose connection problems" and followed the instructions. The final diagnostic is "Windows cannot connect to the internet using HTTP, HTTPS or FTP. This is probably caused by firewall settings on this computer. Check the firewall settings for the ports HTTP...etc." Where on this earth are they?!

I checked the Windows Firewall settings and found it "off (not recommended)" so I switched it on.

I re-ran the diagnostic on the IE page and nothing has changed.

How do I check the settings for HTTP port (80) and HTTPS port (443) and FTP port (21)? Also what do I set them to?

What do you mean by changing COM1 to COM3? Do you want to move a device? Reassign IRQs? Physically pick one up off the motherboard and move it?

Your modem sound is usually configured in two places. One is in the Control Panel, and the other is in the Dial-up Networking settings. Adjust the volume there.

Are you running Windows 2000 and Windows 98 on separate paritions (drive letters)? If so, you'll need to use special software to convert the FAT32 file system to NTFS. I believe Parition Magic will allow this without data loss. However, I would never make such a large system change without first backing up data. There is always the chance that everything could get wiped out.

Hey Guys,

I have been messing around with Apache from (XAMPP) on my Windows computer. I know that it is not secure, but I am just testing it for right now (for fun).

I am behind a Linksys WRT54g router. I can easily access the apache server from internally (locally), and in order for me to be able to access it externally (external IP in address bar), I have to port forward in my router.

So, I port forwarded port 80 and everything worked fine. I just had a question about this.

Since most internet (HTTP) traffic is served through 80, and I just port forwarded 80 to one computer, how do the other computers on my network still have access to the net. Don't get me wrong, it's awesome that this works, but I would just like to know how. Theoretically, wouldn't all the traffic that is coming through 80 be routed to that one computer?

Can someone explain this to me?

Also, when people use Apache to host sites, do they usually keep the apache ServerName (in httpd.conf) at localhost, or do they change it to a different IP? I would imagine they would keep it at localhost, so what would be the reason for changing that to a different IP?

In pictures I've seen on the internet there is a "Device Advanced Settings" button (as seen in this picture but my program doesn't have this.

I doubt very much if this will be possible. The mic and headphone ports are wired directly to the Audio section of the motherboard, there connections cannot be altered.

In Network & Sharing Center, I see it's an unidentified public network with no internet access (IPv4).

I'm at a loss on how to fix this. Anyone know what I'm missing? Thank you in advance for the help.

I have trouble as described in the topic,
I have two most old laptop models, Dell Precision M6300 & Dell Latitude D630.
When laptops is docked to replicator potr dock stations D/APR (PR01X) or D/DOCK (PD01X) - bigger one model with DVD port,

headphone jack port not working under Windows 10 Pro x64 installed on both laptops.

On M6300 previously was installed Windows 7 Ultimate and on D630 was Windows 8.1.
On Dell  M6300 on Win 7 Ult. headphone jack port worked properly.
On Dell D630 on Win 8.1 I'm not sure due I do not used this on it (more years ago when it was on Win XP headphone jack port worked properly)
So when Ms start delivering updates do Win 10, I did it on doth laptops, everything on both models working fine, but only this headphone jack port in D/APR (PR01X) or D/DOCK (PD01X) wouldn't like to work when I'm dockind Dell M6300 (D630 I docked only
for test if on this one jack port will work or not) but not working too like on M6300.
So loks like drivers whih was made oryginally for Win Vista x64 ale which was workable for Windows 7 64b wouldn't like to work on Windows 10.
Maybe You have some tips what to do with this to press them to work?

I have been using an DSL Siemens speedstream 6520 router at home. I usually carry out some R&D by placing servers behind the router. I access the services on each of the servers from the ouside using port forwarding and it has been working fine for http, ftp, RDP, any user defined ports etc but in the case of port 25 SMTP its not working at all. I have checked the port on the local lan and I am able to telnet to that server but from the outside only on this port 25 I am not able to telnet. But If i were to change the SMTP port number from 25 to any other port like 24 or 26, I am able to telnet from the outide. Is there any way i can make SMTP port 25 to work and access the same from the outside.


A:SpeedStream 6520 DSL Router - Port forwarding for port 25

Is it possible that port 25 has been blocked by your ISP? This is a pretty common thing for ISP's to do as a SPAM prevention measure.

As you can see, there are quite a few ISP's blocking port 25 on this list.

Hello, I am an IT Technician for an electric cooperative. I am having a very odd issue that I can not seem to resolve and I am in need of assistance.

We have 4 Dell Latitude notebooks all running XP and we also have some very high end GPS units made by Trimble that we are going to be using to stake out points on a map. Whenever I connection through bluetooth with the GPS I am able to pair but the GPS control software never recognizes it when I chose the COM port assigned to it. Whenever I connect it directly through a cable(serial to usb) it never detects it either.

However this is the odd part, when I test this on my desktop I am able to connect just fine with the exact same method.

Any ideas?

A:router not passing port scan after opening port

Have you tried a different port to see if that port is being blocked by your ISP?

I also see that your parsing TCP to UDP, probably doesn't make a difference to the port being open or closed but it might be better to set them both the same or set to Any.

Another problem you may encounter is your IP may change, most ISP's like to change your IP every so often so you may have to set up a DDNS with a hostname in order to access the services you want remotely.

I have had the worse luck with this laptop, the most recent problem that I'm experiencing is I tripped over my printer cord and ripped out the plastic tab inside the USB port. I know that I can't fix it on my own, but I would like to know how much this problem will cost to fix. I've called around to ask about repair costs and everyone keeps saying I need to bring it in for an estimate. But I need my computer for work and can't leave it overnight. They say that it can be repaired one of two ways, either the manufacturer has a separate card that can just be replaced or it actually has to be manually repaired. I just want a general estimate for how much it would run for either/both ways it could be repaired, as well as how much it runs for labor costs.

Also the memory card reader has not worked since January, I know thats not related but I'm just wondering if there is some defect in the ports.... or if I'm just destructive.

I have two PC interfaced USB multimeters of same model (MASTECH MS8340 B). For my research work, I have to record voltage and current simultaneously with time with these two multimeters (as this is having data logging options). One meter assigned to record current in PC and the other one record voltage in PC. Operating system: Windows 7, 64 bit. When current measuring multimeter alone is connected to a PC via micro USB-USB cable, it records current as expected. And similarly, when voltage measuring multimeter alone is connected to PC via micro USB-USB cable, it records voltage as expected. But if the two multimeters are connected to a PC in two different USB ports, and if the program is opened to record both current and voltage data, it shows an error says ?Port error, Port already open?. The point is both meters are connected in separate USB ports. Now to record the results I am using two computers one for each.
Is it possible to connect the two (same) USB multimeter devices in a single PC? Kindly post solution.

Ok, so I'm pretty much a neophyte with XP - we only have one computer with it (what's up with all the cartoony features?). We have one port that's definately named "com port" on the computer - a male 9-pin port (there are others that appear to be named "COM" up through #6 but which exactly those are, I am unsure).

We've got a port that's labeled as LPT1 and it's a female 25 pin port. We've got the latter (the LPT1) equivalent assigned as com ports on our other computers (which run on 98SE). We are looking to assign the LPT1 as a com port in order to get a specific connectin for some software we are running. Problem is we can't seem to get windows XP to see the LPT1 as a COM. When we've tried it labels it as a COM port with a big ol yellow question mark and it doesn't work (meaning communicate with the device and/or the computer itself).

So anyone know how to give me more information and/or instructions on how to reassign things (we need it to be com 1-4, probably will need to reassign the other things named coms 2-4). Oh it's a dell inspiron 7000 - notebook computer if that helps and/or changes things. Let me know what other information I need to provide and I will do.

Original problem is intermittent motherboard RJ-45 Ethernet socket plug,

I recently purchased a ( made in China ) CN008L USB to RJ45 Adapter dongle which came in the box with a mini CD. The software on the CD does not list WinXP 32 and the instructions ( what little are in Chinese ). The dongle is compliant with USB 1.0, and 1.1, and 2.0.
So theoretically it should work to use a USB port on the computer to connect to the old D-
Link DSL-300i ADSL Ethernet Modem thereby bypassing the need to use the intermittent
motherboard RJ-45 socket!

I downloaded upgrade drivers to allow for win XP 32 setups and downloaded the drivers but
no luck so far.

Is there any reason that I should not be able to setup and run PPPOE or other software over
the USB interface in stead of the RJ-45 Ethernet port. You people should have someone there with that "savoir faire".

To date I have not managed to find PPPOE software that pre-selects USB channel rather than RJ-45.
The setup for my wireless TP-Link 54 Mbps is connected to the USB port and works well but I did use setup disks specifically designed for that product.

The thread I found on here stated the following:

I work for an organization with about 300 employees and almost all have computers. I have experienced the following issue on several machines over the years and still cannot find an answer anywhere on the internet, so I am posting here.

I have an HP business desktop that has two parallel ports in it: LPT1 and LPT2. On a rare occasion the printer connected to LPT1 will jam and I have to clear the paper out of the paper path. After I clear the jam, the computer is no longer able to print anything to LPT1. If I use the application that prints to LPT1 again, I get an error in the application stating "The requested resource is in use. (170)" Others on the internet have reported similar errors and in a few cases, the exact same error, but no luck with a solution. Further, there is no error in the Event Viewer's application or system logs.

So, I have tried:
+ uninstalling LPT1 port from the Device Manager, reboot, and still no luck. Same error.
+ uninstalling LPT1 port from the Device Manager, shutdown, disable the parallel port entirely, boot into Windows, shutdown, re-enable the parallel port, boot into Windows. Same error.
+ Reassign LPT1 port to LPT3. Same error.

1 intake 120mm fan on left side panel--
2 exhaust 120mm fans on the rear panel--
plus the exhaust fan that came on my power supply.

with 3 fans blowing out and 2 fans blowing in---I wondered if I should install a fan
in the blow hole slot.

this case has the screw holes in the top of the case for a blow hole.
but didn't come with a fan preinstalled.

should I go ahead a install a fan here and would it be better to turn
the fan around to make it a intake fan instead of a exhaust fan????
do I need more air coming in to my case with 3 fans blowing out??

or just leave the blow hole slot empty.

my case came with fan speed control knobs on the front of the case.
I have bought replacement Antec fans to connect to the motherboard.

during my vacation next week I'm going to through away the fans that
came with the case and install the Antec's

I'm starting to believe the motherboard controlling the fans would be a better

This is basically for my father, his numbers on the key pad to the right of the key board are not working. In the past I have checked several options and ended just hitting some keys (i.e. alt F4) until one of them seems to work. Now he is having problems again. Is there something else he can do?


A:Key pad numbers

is it possible that you have pressed the number lock key, this is situated on the row above the number keys...mine is above the number 7 key.

press it and see if this solves the problem

What you describe can be a sign of the keyboard going bad. Are letters affected when you type those?

Do you have access to another keyboard you can use to see if it also happens with it?

I want to upgrade my laptop RAM from 4 GB to 6 GB. Before buying the 4 GB RAM I have to know the exact pin of the RAM, and I don't know the exact numbers of pin in the RAM. My laptop is Ideapad Y550 4186. So how can I know the numbers of pins in the RAM without having to open the case? Please help!

A:How to know numbers of pin in RAM?

It's 204 pin, but you need to know more than that.

That's a Lenovoe Ideapad Y550. I entered that make and model into the configurator at and it came back with the following compatible RAM choices for that laptop.

3 of those choices are for 2 GB sticks.

You can shop for those same Crucial part numbers from your source or buy 204 pin RAM from another brand as long as it has the exact same specifications.

I hear that soon we will all have a personnal ip number. IP version 4 or something similar? Is this a good thing?

A:IP Numbers

Where did you hear that?
There are too many people for individual IPv4 numbers. IPv6 could do. But I still doubt that.
It's a Bad Thing if something like this happens.

My system is an IBM P4 3.2GHz running Windows XP Pro SP3. When I power the system on, there are some Hex numbers that appear at the lower right of the monitor screen such as 003B, 0075, 0078, 0073 and probably several others that I can't see because they come and go rather quickly. Does anyone know what these numbers mean and is there a problem with my system because these numbers appear?? My system appears to boot & run correctly and there are no hardware or software problems that I'm aware of.

Thanks for any help here.


A:What do these numbers mean??

Do they appear and change when you move your mouse? When you press a key on the keyboard? It looks like it could be some type of debugging information but nothing harmful.
