Help!! Modem/Com Port

Okay, I recently built my first PC and it has been running well, that is until I tried last night to get online.
I doubt it's a massive problem but I'm stumped. I'd really, really appreciate some help on this one.
I have a K7N2 Delta-ILSR, and I'm trying to run a Creative Modem Blaster V.92 PCI modem.
Right now my PC says it's on slot 5.
Anyway, whenever I try to connect to the net, via AOL (sucks I know, but I get it free where I live), the thing just doesn't dial. I think maybe it's a com port problem, but I know nothing about them. I bought the modem OEM, so no manual. It's showing up on Com Port 3, and the PC says ports 1 and 2 are 'In Use', though I don't know what with.
I initially had it on another PCI slot, installed it with the CD which came with it. And I had the problem. I moved it to where it is now, and before reinstalling with the CD the modem would dial, but was only recognised as a Generic modem. It also wouldn't talk with the network. So I reinstalled with the CD, and then I was back to square one.
Any ideas?
Here's my set-up:
K7N2 Delta-ILSR
Win XP Home
Athlon XP 2500+ (no o/c)
2x 256 PC3200 Corsair RAM
Radeon 9500Pro
Please some help would really be appreciated.

Hi,
Dial up modems can be a bitch to install (don't ask me why!). Try this: Power down and remove your Modem card then uninstall any drivers you've installed for it. Reboot then re-install the modem driver software (I assume you have drivers) then power down again and replace the modem card. Hopefully when you boot XP should detect your hardware and then install the drivers you've installed!
Also turn PNP OS off in the BIOS, and make sure APIC is enabled.

Internal Modem Com port!

hi,
I was designing an application in which i should check if the modem is active or NO. I had a simple idea which was to try to open the modem's COM port and if I get an "port in use" exception means the modem is active. I used the comm API but I found out that my modem's COM was not listed in the port ID and I suppose it is because the modem is Internal and doesn't use a Physical COM port like the serial port but a virtual one.
Is there a way in which I could access this virtual com port??
Thank YOU
adel

Try the API for port.info() and Line

Unable to create the bluetooth virtual COM port

Hi all
I install BS from Toshiba and it seems ok. Bt ir desn´t work. I see all the drivers installed, system devices, etc. No Toshiba BT ports can be seen. Local com ports only show modem port. Try to create a virtual port but get a message "unable to create a bluetooh virtual port" I have a satellite m100-145. Can anyone help on this ?
thx

Thx for your suport.
I decide to reinstall windows and all software. Now it works.
The error was due to the fact that if you have BS from Microsoft (called bluetooth monitor) and you install the BS from Toshiba after that, even if you remove the BS from MS, the BS from Tos is unable to create the virtual com ports (except modem).
I try with the latest version of BS and the problem was not solved. So if there is a previous installation of BS fom MS the BS from Tos get the message of "unable to create the bluetooth virtual com port".
Now i fixed reinstalling SO from beginning.

COM ports configuration

I need to connect a PDA Fijitsu Siemens Pocket Loox to the PC using the Bluetooth. I have successfully installed software for the dongle on the PC side BUT there is a problem to connect PDA to the PC using Bluettoth Serial Port. PDA Bluetooth software (Pocket PlugFree) is ALLWAYS using COM5 but this port on the PC is not available because it's occupied by Bluetooth Fax Modem installed from the dongle installation package. If I disable the modem then COM5 is still not available (niether COM6 and COM7, which are also blocked for Bluetooth Modem and Bluetooth Null Modem and also can't be reconfigured). Please, don't you know how to reconfigure COM ports for the dongle?
I use Windows XP on the PC. Both devices can communicate to each other and files can be transfered with no problem.

Hi
I had the same problem with my T61 and my HTC Touch Diamond, and found the help I needed here: http://lopsa.org/node/788
It did not work the first time, I had to do I a couple of times, but it finally worked out.
Hope you get your problem solved.

Multiple COM Ports after installing to peer to peer Brother Laser Printers.

My particular situation is one Iv'e never encountered in thirty years of working on micro-computers. I have a peer to peer LAN hooked through a Gateway (4-Port \ WIFI (Frontier=Telco) ADSL\MODEM\Router made by Net Gear. I have 4 Wireless ip's and 3 cat 6
wired ip presences on the LAN. All the network is MS WIN 7 64 bit software and all the computers are 64 bit hardware, I have the home Group numbers matched up and everything shared on the LAN side of the Gateway. The problem on one of the clients (Dell
Notebook, 2 years old) is that when I installed the two cd's with the Brother suite of software (HL-2270 DW Monochrome laser printer and a (MFC-9130 CW Color Laser all in one Printer\scanner\fax\copier everything was fine for a while until the two printers
began to jump their dynamic assigned IP's. So, I statically assigned on the two printers with the ip address they worked on after rein stalling both software cd's ; uninstalled the old software first of course. I am hunting for a fix, something in the OS or
Registry short of a clean reload of the whole Dell notebook to bring the ports back to 3 LP and 4 com ports! They read 4 lpt ports and 24 COM ports presently.
Thanks For You Time,

Have you gone into Devices and Printers, right clicked on one of the printers and selected "Printer properties" and then the
Ports tab and tried deleting the unwanted Com ports there?

Problem related USB Virtual COM PORT using PDA module 8.2 on Windows CE

Hi,
I am working on tranferring my application developed on LV 8.2 to a Single-board computer(SBC) running Windows CE 5.0. I am using LV PDA module 8.2 to achieve this. My problem lies in finding the port number of the Virtual COM Port on the SBC. I need to connect a USB RF modem from Maxstream to this SBC and to talk to it using VISA. I have installed the required drivers from Maxstream for converting the USB port to a virtual COM PORT. What is a way to figure out the COM PORT number on a Windows CE device? For a PC, I can see the COM PORT in the device manager but I do not know how to find this in Windows CE. . Also, I have tried using "VISA Find resource" function ..it works on a PC but I do not get anything in the Win CE device.
Any help would be much appreciated.
-Shruti

Shruti,
Is there a way to verify that the Maxstream driver successfully provides you with this virtual COM port? Essentially, what I mean is that if you did not have LabVIEW on this device, how does Maxstream prove that their driver is functional? Does it come with additional software that would be used to configure the USB RF modem? In any case, we would want to try opening any terminal program (like the hyperterminal) to determine what ports are listed for communication. I hope this is useful for you. Please post back when you are able to give this a try. Thanks,
Mike D.

CISCO ISDN TP Link is not connecting on COM port

Hello All,
I am having CISCO ISDN TelePresence Link. I am connecting it through COM port I changed the serial port settings as per recommended settings shown in User Manual in my laptop but still console is not coming. Please help...
CISCO ISDN Telepresence Link 1.1
Regards,
Kiran Chavan.

Make sure you're using a standard serial cable, and not a cross-over/null-modem cable.
Double check that your terminal settings are correct for 115200, 8, 1, none (as per example PuTTY screenshot below).

Write among COM ports in the same PC without cables

How can I write to the memory address(es) of a serial COM port? I would like to send data from one serial COM port to another in a manner similar to the that of the 'Simple Data Client' and 'Simple Data Server' vi examples. This must sound strange since this is exactly what a null modem cable will do, externally. I would like to eliminate the cable connection between COM ports that exsit in the same PC and communicate between them, internal to the PC, somehow.
Currently, I am using a LabVIEW vi to read a serial message on COM1, translate it, send the trsanslation out on COM2, so that a separate windows program (no .DLLs to interface with LabVIEW) can read the message on COM 3. COM 2 and COM 3 are connected by a null-modem cable. This requires three COM ports, and two serial cables. I realize that I can use a physical loop-back jumper on COM2, for instance, where I send and read the translated message on COM2, but I still wonder if there is a method for doing this in memory, or something. Is there a way to accomplish the same objective with one cable (into COM1), no loop-back jumpers, and only two serial ports? In summary, I want to read on COM 1, translate in LabVIEW, then write directly to another COM port, internally, without using a serial cable. Can the 'IN PORT' or 'OUT PORT' vi's apply here? Are these tools only for parallel ports?
Hope this is not too confusing.... It seems like I am always trying to do something with LabVIEW that was not meant to be done....
Thanks.

Thank you. If I pay the price they ask, this looks like it will create and share virtual COM ports - exactly what I need. However, I would really like to find a way to do this in LabVIEW, such that I do not have to make my application dependent on another piece of third party software. The 'Simple Data Client.vi' and 'Simple Data Server.vi', included in the shipset examples, seem to do this for TCP/ IP ports. I wonder why the COM ports cannot be addressed at the memory level, in a similar manner???

How to use shared variables to address multiple Watlow controllers on the same COM port

Hello,
I am trying to use LabVIEW 2010 to control 4 Watlow temperature controllers on one COM port. 3 are Model 96 and 1 is an EZ zone controller. Each controller has a unique modbus address, and I am trying to read from and write to individual registers (such as closed loop setpoint) using shared variables. I am getting return data when reading (although the data appears to be invalid), but am unable to change the value in the register by writing. How can I be sure that the Modbus server is sending commands to the correct controller?
Chuck
Solved!
Go to Solution.

Peter,
Thanks for the reply. I have actually solved that problem. I realized that the Modbus server address has to be the same as the controller's Modbus address.
I have, however, run into another problem. Perhaps you could help me with that. I have a system with 4 Watlow controllers, 3 are series 96 controllers, one is PID only and 2 are ramping. The 4th controller is an EZ zone. I am using RS485 for communications and the controllers are all wired in parallel for communications and power.
I have set up 2 Modbus servers for 2 of the controllers.
This is the first I have ever worked with Modbus based communications. I have successfully programmed using the Modbus read/write VIs, and am wanting to move to shared variables. My questions right now revolve around addressing, Modbus I/O servers and COM ports. Specifically, at this point, I know the addresses need to match up between the server and the slave device (Watlow controller in my case), how many servers can I create and use on one COM port? If the number is limited, is there a way I can specify an address that I want the server to talk to? Will the broadcast mode work to request data values from the controllers?
I'd appreciate any information you can help me with, or if you could point me to some sort of concise 'How-To' for Modbus communication.
Thanks.

HyperTerminal sees a COM port but VISA does not

It should not be possible that HyperTerminal sees a COM port but VISA does not. Does anyone know why or have any ideas?
Here's some more info: I wrote a LabView (LV) program and deployed it (via the Application Builder) to some of our production department's PCs (some Windows XP and some Windows 7). We use it to set up products we design and manufacture through our device's USB serial port. The USB port is actually a virtual COM port (VCP) - a USB to Serial converter or "bridge". We have a custom driver for our device and since each device's USB bridge chip is programmed with a different serial number, every time we connect a new device to the PC the installer runs and assigns a new COM port number. This is so our customers can use multiple devices on a PC. Fine. On one of our production PC's we were close to COM900 ports (HyperTerminal sees only up to COM256) when suddenly Win7 would not allow any more. We were able to uninstall orphaned (non-present) COM ports from DeviceManager ("DM") by starting it from a command console (DOS window) with a special command-line switch, "set devmgr_show_nonpresent_devices=1" then "start devmgmt.msc" (I have this in a batch file). In DM View menu you can "Show hidden devices" and uninstall them as if they were connected. I've also tried uninstalling them the normal way when the device was actually connected. Either way, sometimes, not always, depending on the COM port number, after reusing that port number by installing a new device which picks up that old, freed-up number, LV VISA doesn't see it. In other words, when "Refresh" is clicked in the COM port VISA list box, any new devices installed should be and normally are seen. (Refresh is not needed if the application is started after the device's driver is installed. It is only need if the LV application is open with the new device is added.) However, HyperTerminal does see it and lists it in the Properties screen, the "Connect using..." list box. And the port works with HyperTerminal. (Of course we've tried rebooting after uninstalling and/or reinstalling the device, with the same results.)
When I've spoken to the NI Applications Engineers in the past about serial port issues (not about this problem) they have confirmed that if HyperTerminal can see the port then NI VISA should also see it. This is crazy. I am posting this in hope that someone can shed some light on this problem.
Thank you. -Ed

Good catch. Yes, we're using the Silicon Labs CP2102 and have created a "custom driver" installation package. Our new PCBs have a factory-programmed chip, so the PC reuses that COM port (COM3 on that PC). The problem is when we we re-program the CP2102 (setIDs exe) with our PID, and device strings (including the S/N), the PC runs our installer and assigns the next COM port number. I was hoping that maybe it would go up to 64K or something! Anyway, it surpassed COM256 but we ran into this problem when almost up to COM900.)
There is a registry entry for each SN device, which shows the assigned port. If we delete the key with regedit, the COM port database (don't know the file name) still has the port number. That's where Device Manager comes in. It seems to allow us to manually delete the ports, but it would take quite a while to delete 900. (I was trying to make a batch file for DevCon, but couldn't get it to see the HW ID of the devices in need of deletion.) So we tried manually deleting a few. After doing that Device Manager shows that Windows (and HyperTerminal) can reuse the port number when a new device (new SN) is installed, but, as you know from this post, VISA cannot see unless I manually add it in MAX.
I can't see how it has anything to do with the Silicon Labs driver. I might have to delete ALL of MY devices, then uninstall the driver files, reboot, then reinstall, as you suggested with the SiLabs driver. However, I don't see how VISA will now see these changes. VISA must have it's own database. That's what I thought deleting the ports in MAX would clear out, like a fresh install, but apparently not.
I've been through Silicon Labs' tech support on other issues and they've been able to help on some. I could run this by them.
BTW, have you noticed that Silicon Labs' chip and driver, while faster than NI's own "bridge" or serial-USB converter (I returned it because at $100 it's performance was worse than a $20 converter you can buy in Staples), is substantially slower than a real serial port? For example, our device can transmit 250 readings per second (a 12 byte string). A real serial port used with my LabView program can keep up, i.e.., graph & tabulate at that rate, but with a VCP we only get about 70 RPS. Same code. Can't figure this one out. They say the've tested the driver to 900 KB claimed. We're using 115KB here. Anyway, the VCP driver makes it look like a COM port which LV thinks it is. Why is it slower than a real port when the USB should be able to work almost 10 times faster than I'm using it (up to 1024 bytes per mSec per the full-speed USB spec, which SiLabs claims they verified)?
Anyway, I appreciate your help. Thanks! -Ed

Problem with Com port

Hi guys. I have written a driver to communicate with a COM port (FTDI serial adapter). On the pc from which I'm writing now (windows XP) it works properly, but when I try to use the same driver on another pc (win 7) labview see the port but isn't able to comunicate . I tried also to use a software like Tera Term to see if the com works and trying the echo it works good...so I don't understand where the problem is on this w7 pc...
should I install some labview drivers on the w7 pc? I have already installed
NI run time installer
NI max
NI Visa run time

NI Serial won't help (its for NI serial cards not 3rd party USB-Serial bridges)
LabVIEW sees the VCP in Win7 but does not communicate: Works on XP: "Something" happens with Echo on from teraterm.
I'l guess either:
Wrong serial cable or settings and you are fooling yourself with the tereterm app and are seeing the echo only. With Echo on any character sent should be doubled.
Outdated FTDI Driver that does not support Win7.

Problem with COM port opening

I made an application using COM port to dialog with a microcontroleur and i have some troubles with the opening of the port. i developed it under window XP pro and labview 6.1 and i have no problem when i launch my application on an XP PC having labview installed or on a window 98 PC without labview (just the runtime engine). But when i launch it on an XP pc with only the runtime engine, it seems to launch correctly but in fact, there is a problem with the COM port opening. The menu allowing to chose the port number is inactive and has no effect, like if the software wouldn't recognize the material port on the PC. And consequently, nothing happens when the dialog should start.
Thank tou for your precious help

Is the VISA run-time engine installed? I don't understand why it would work on the win98 machine unless you have an older installation of it there.

Satellite A300-1BZ with Vista - Com Port has disappeared

Hi everyone.
My first time and I'm a bit of a duffer with technical stuff, so please be gentle with me!
A300-1BZ with Vista.
A while ago I installed 'CarSoft V.83' (Engine diagnosis) from CD onto my laptop. It asked me to verify the com-port.
I looked in the device manager and in the list I saw 'com-port 4'. Ok, we'll go with that then. Everything worked fine and I was happily talking away to my car.
Yesterday I went to use it for the second time and it said there was an error with the com-port and to 'verify' the com-port.
So, I got the device manager back up and there is no mention of any com-ports in the list! It was there the last time I looked and now it's vanished!
I was at a loss what to do so, I uninstalled the CarSoft and then re-intsalled it again. Got the same error message.
Went to device manager. Still no com-port 4 in the list, or anything that relates to a com-port.
I don't know how or if I can get it back.
Please help!

Hi mate
First of all there are no com ports. The com port which you could see in device manager was an virtual port created by car software.
What to say
I recommend removing the car software from the system firstly.
Then download the CCleaner and clean the system and registry entries.
Reboot the notebook and run the CCleaner again
After that install the car software again
Maybe it helps
