Installation Guide

[kaznad]

Hi, Please advise how do I install this service? Thanks :)

[albertjan]

After you've installed .net 3, 3.5 and 4. You can run %WINDIR%\Microsoft.NET\Framework\v4.0.30319\InstallUtil -t Path\To\NP2COMS.exe

Use NP2COMV to make a .n2c file drop that in the Path\To\NP2COMS.exe

delete example.n2c

run: c:\>net start NP2COMService

or go to services and start it.

Goodluck

[kaznad]

Hi Albert,

Thank you so much for your help. I am able to install it now.

Now I am not sure how to use the NP2COMV tool.

I would like to install a GPRS Modem. How should I go about doing it?

Lastly I would like to thank you again for taking the time to send me the
installation guide.

:)

Regards,
Zak

Hi, you create a virtual comport on your virtual machine using the settings dialog like so:

remember the name you gave the serialport on the virtual machine here

this is what you look for in the combobox on the left in NP2COMV:

on the rigth in NP2COMV you use the correct SerialPort settings (they're probably correct as default).

Then you press Write config file. This writes a n2c file to the directory of NP2COMV.

Copy this file to Path\To\NP2COMS.exe remember to delete the example file.

[kaznad]

Hi,

I have an error message when I click on test. I followed your example.
Named Pipe has been assigned as comport. and the Namedpipe in the NP2COMV
is also sert as .\pipe\comport I get an error as below.

This exception occurs when the selectedItem of combobox is empty. It's probably a bug on my side, I'll have a look at it. To fix it in the meantime: select the correct namedpipe from the combobox instead of typing it in. I should be in the list if the virtual machine created it.

Remember NP2COM should be run on the host machine. Not on the virtual machine.

[kaznad]

Hi,

Thanks for the advice.

I tried the named pipe from the list which is lsass. I entered it in the
hyperv settings as well.

When I tried to use the GPRS modem in the virtual server i did not work.

How do I test if the service is working? In the tool, when I click test,
nothing appears below. This is when the NP2com server is stopped. If the
service is started and I test, it crashed.

Any way to test this?

\\.\pipe\lsass is a system pipe. Do not touch. just name the pipe comport like I showed you in the example. Maybe restart your virtual machine. After you've done that, start NP2COMV now \\.\pipe\comport should then be in the dropdown list. Then try it.

[kaznad]

Hi,

I tried to use the pipename comport in both the vitual server settings and
the write the config file pipe name as comport as well. When I tried to
click on test on the NP2COMV tool, i get a com1 access denied. Then I tried
to stop the NP2COM server and tried again the button change from test to
testing but there was no output in the bottom. The modem does not work as
well.

Please advise.

Hi,

It finally works!

It was a stupid mistake on my part. I should have used com port 3 instead.

The only thing now is, it sometimes doesn't work and I have to restart the
virtual server.
Is there anything I can do to fix this. Once the server is live, it is not
practical to restart the server.

Hi,

Thats cool.

It's absolutely not practical to restart the vm once it's live.

But I need more information than "it stops working".

Do you have a logfile with such a failure it in? NP2COMS should log some stuff.

Does it happen at random or when you do something special?

[RanmaKei]

I notice it loses communication in a 24 hour period. Currently, I have a task scheduled to restart the service in 24 hours, and then it is able to reestablish communication. Also restarting a VM seems to also break the communication, so I have a shutdown and start-up script on the VM to restart the HOST's NP2COMS service. I'm not sure if this is bad to restart the service when the port is constantly being used, but it seems like the only option to make it reliable.

[albertjan]

@RanmaKei Does the service crash or does just "stop working"? Restarting the vm resets the namedpipe I'll have to look into that, I think I should be able to see when that happens and then reconnect to the pipe. I'd expected to get an exception when the connection is dropped. What do you use as a vm os?

[norm8332]

Hello, First I'd like to thank you for this program..I have it working but as above while the service continues to run it does stop functioning at one point. I'm still testing to attempt to find out when and why but I believe it is when my host backup of the VMs runs. It suspends/pauses the VMs for a minute. restarting the np2coms service makes it work again without restarting the guest. The guest OS in this case is QNX 4.5 (linux -like) OS. Thanks

[albertjan]

Hi! @norm8332 you're welcome. I have to setup my dev environment for this I think I can check what the state of the pipe is. And then when it goes down restart it asap. I don't think I can asure not to drop any bytes. Most com applications aren't really fault tolerant they don't expect the connection to be down. So I don't know wether or not your guest os and the application there will handle this correctly.

[hicham47]

Hi !

i have probleme to start the service NP2COMService
and access denied with com1

thanks to help me

ps : 2008 R2 server + Hyper-v and VM = 2003 server

[albertjan]

Have you tried running it as administrator? Isn't there another program using the comport.

[hicham47]

yes local account running service is local administrator and comport is not used

thanks

[albertjan]

the other pipetocom app is also off?

[albertjan]

Windows is almost always right here. You either don't have enough rights or it's used by a different program.

[hicham47]

I have tested it in my pc running W7 Pro 64 : i have running CMD as administrator and service runs with no problem

i'm trying to unstall and re install to in my 2008 server

thanks

[hicham47]

on the 2008 server I still have the same problem although the service is installed as administrator

[albertjan]

Can you post the logs too? Have a look at this tool if you can get some more info.

[albertjan]

Are you sure there is a COM1? and are you absolutely sure nothing else uses the comport?

[hicham47]

There are COM1 and COM2 and no device connected at time
PORTMON says "not connected"
and when i select COM2 on the NP2COMV.EXE it says "No response" and crash

[albertjan]

when you start to service you should turn np2comv off. Other than that I can't help you any further.

[ghost]

Hello
I have a problem.
I run this OK:
%WINDIR%\Microsoft.NET\Framework\v4.0.30319\InstallUtil -t Path\To\NP2COMS.exe

Then i run NP2COMV to generate new config file. I setup parameters and try to save. I have an error on the screen.

I have installed Microsoft .NET Framework 4.5.1 (4.5.50938)

Please help me...

[eddelac]

I've followed the install steps with success, registered the service, created the named pipe, created the config file using the named pipe, saved the config file on the same path, deleted the example config.

But the service stops just after starting it. The virtual machine is on. I'm im missing something?

[dcrowson]

I found this to happen if the device using the com/serial port wasn’t running or connected.

[eddelac]

@PiterEL I had the same problem, it seems to be related with the folder permissions. Try running the program as Administrator.

[albertjan]

@PiterEL It might be due to the fact your running vmware. It creates a namedpipe with a weird name. @eddelac Might be right aswel.

@PiterEL the config files are really easy to edit by hand. have a look at example.n2c you can probably edit that to fit your needs.

[albertjan]

@eddelac did you fix your problem? There is a log file in the directory. If you could open a new issue and post that logfile there. I can have a look and see whats going wrong.

[fgmike]

Hi,

Getting the same error as @PiterEL. The named pipe in the example file, should I change that from com to .\pipe\comport for example?

How else should I edit it, as I cannot see an existing named pipe on my Hyper-V Server 2012 R2 listed when I run np2comv.

Any chance also of fixing the image examples in your setup instructions above? I could not see it to compare.

Trying to get my head around these named pipes is causing some extra grey hairs.

Any help Appreciated.

[dayers]

Just set this up successfully mapping a hyperv vm com port to a physical com port. I followed the steps below in order:

1. Install tera term on host machine to give you something to test your terminal connection with.
2. Install driver for usb to serial cable if required.
3. Insert usb to serial cable.
4. Launch tera term - select serial - check com usb to serial cable inserted in is port listed. Use device manager com ports or at a command prompt type c:\change port /query.
5. Install NP2com - You can run %WINDIR%\Microsoft.NET\Framework\v4.0.30319\InstallUtil -t Path\To\NP2COMS.exe.
6. Create named pipe for vm - launch hyperV manager - highlight VM (vm off at this point) - select settings in lower windows - com1 - enter a name for pipe e.g comportvm. Leave remote computer box inactive.
7. Start VM (login not reuired at this point).
8. Run NP2com\NP2comv.exe as an administrator to create a N2C profile;
   Select pipe name from right named pipe drop down box - comportvm - this is near the bottom of the list
   Select the settings you want to use -serial port, baud rate, stop bits and parity i.e com4, 9600, 8, none, 1
9. Select write config file from options on right hand side.
10. Name and save the file in the NP2COM folder. This is the config file associated with the named pipe from the VM.
11. Goto services on the host machine and start the NP2COMService. (USB to Serial Cable must be connected at this point).
12. Logon to vm - install and launch tera term - select com port to use for connection - hit return until output returned.

issues

Named pipe created on VM will net be visible in NP2comv untill vm is started;
NP2comservice will not start unless usb to serial cable connected;

albertjan,

I have a questions regarding the install and I am hoping you or someone here can assist me, do we need to complete this installation on both host and guest?

[albertjan]

Do you have .net 3.5 and less installed? ;)

I have 4.5, I was able to install and start the NP2COMS service successfully after I posted my questions. ;)

I was asking because I couldn't get the service registered but found that I had to unblock it. Please bare with me as I am a system admin and have very little programming knowledge.

BTW, thank you very much for the quick reply and for your work, we greatly appreciate.

Once I have it installed and start the service, can I just go ahead and start using the guest's COM port or do I also need to install it on the guest?

[albertjan]

If you hooked it up to the correct namedpipe you should be fine.

I do all step by step as @dayers describe and i run Hyper-V machine. How i can test and add Faxmodem to machine Hyper-V ? Please help me...

On physical machine service NP2COM works ok. Please help me because i want run service serwer fax on my virtual machine Hyper-V.

[vibac]

Hello albertjan,

All is good!!! Thanks :)

I will post all my steps, please let me know that's ok with you.

--How to Install NP2COM--

Give your user full rights on the NP2COM folder after extracting it
1- Right click the NP2COM folder>properties and give your user full rights
1a- You can put this folder anywhere on your server, ie: C:\NP2COM\

Ensure that the NP2COMS general properties are unblocked
2- Right click the NP2COMS.exe>properties at the bottom hit the "unblock" button

Register the service NP2COMS
3- After you've installed .net 3, 3.5, 4 or 4.5 you can register NP2COMS.exe as a service by applying the following cmd

Start cmd with "run as Admin"
c:\windows\microsoft.net\framework\v4.0.30319\installutil.exe -t C:\NP2COM\NP2COMS.exe
or use run
%WINDIR%\Microsoft.NET\Framework\v4.0.30319\InstallUtil -t C:\NP2COM\NP2COMS.exe

Create the Named pipe in the guest VM settings
4- Right click the vm from within the host's Hyper-V, select "settings", then select com1 or com2, tic "named pipe" and enter a name, ie: comport

Create a config file for NP2COMs service
5- Run the NP2COMV.exe as admin to create a .n2c config file and save it in the Path\To\NP2COMS.exe, ie: C:\NP2COM
5a- On the left hand side select the NamedPipe you created previously in step 4 from the drop down list, ie: .\pipe\comport
5b- Set the serial port settings to your needs, ie: baudrate 9600
5c- Now click "Write config file" to save it and save it in the NP2COM location, ie: C:\NP2COM\

Delete the example config file
6- Delete example.n2c

Start the NP2COMS service
7- Run: c:>net start NP2COMService or go to services and start it

DONE!

Test communication
1- Stop the NP2COM service on host
2- Launch the NP2COMV.exe as admin
3- Go to the guest and launch hyper terminal or putty terminal
4- Once you connect to the setup COM port hit enter
5- Go to the NP2COMV window on the host and see if the data is written
6- Once you are done, kill the NP2COMV process then start the NP2COM service

[sonvoba]

FWIW, I do have .NET 3.5 and earlier installed on this system. Could it be something else?

[albertjan]

@sonvoba no it's a known issue in the np2comv program. There's a namedpipe in the list that contains something I didn't expect when I wrote it.

You could edit the .n2c file yourself.

[sonvoba]

Albert-Jan,

Many thanks for the follow-up. Will the np2com service know where to pick up the correct .n2c configuration file, or should I just edit the existing example.n2c and things will work?

It will pick up any n2c file in the directory. So yeah you can edit example.n2c

Albert-Jan,

Many thanks for the follow-up. Will the np2com service know where to pick up the correct .n2c configuration file, or should I just edit the existing example.n2c and things will work?

How do I disable logging?

[albertjan]

@bschappel delete log4net.config

Quick question regarding the serial settings in the .n2c files. Do those settings hardwire the host comport?

We've go a barcode scanner base station that connects over serial. It needs 9600-8N1. I set this in my n2c file but when I try and connect from the guests OS the software complains that there is a mismatch between the serial port and the required settings.

It may be that your software won't work with this device and that's fine.

I was just wondering if the guest OS can negotiate the settings of the comport on the host.

[albertjan]

@bschappel No it can't communicate from guest os to the np2com software. The settings for the comport in the n2c file are the ones used to connect to the real comport. The settings in the guest don't really matter. But you could be running into a CTS RTS issue. Those settings aren't comunicated to the host os.

Otherwise it's smart to set the comport on the guest os to the same settings otherwise it'll drop bytes, because it sends data to quickly.

Remember to turn off your uart buffer on the guest os.

I set & used this a few weeks back I must thank the owner\creator as after a few issues, this work very well.
I just have one question & it's not a big - after a few weeks it seems the service becomes a little unstable & crashes out. Restarting the service is not a problem, it works again without issue until it crashes. Crashing once or twice a day & having to restart the service isn't that great. Has anyone any ideas as to what is the cause or fix to the issue?

Event log shows a .Net run-time error on each crash -

Hi Albert,

Thanks for program. I managed to get it to work on my XP mode VM, only one serial port though.

Does your program support multiple serial ports? Experimented with several config files, no success.

thanks

[albertjan]

That normally does the trick several config files. If that doesn’t work. I don’t know I haven’t really done much with this for ages.
