This is ridicilous!

Setting up a VM, no matter what it's name, is [color=#ff0000;]always[/color] more complicated than just setting up the HostOS.
The reason is, that for a program to work properly in a VM, the [color=#ff0000;]Hardware - Firmware - Driver[/color] of the HostOS have to work perfectly and then you go on and add [color=#ff0000;]"VM Connection to the HostOS Driver" - "Driver of the GuestOS" - Program[/color].

So unless the drivers arn't the problem, but the program just doesn't work under Win7, there's [color=#ff0000;]NO sane reason to fiddle with VMs!!![/color]

And with those last words, i bid farewell to this topic. I feel a brain aneurysm coming on. ;)

I don't think this is strictly true. A VM can have direct access to host hardware that is not being driven by the host OS. There does need to be a host driver for the VM's direct access, but it could be generic, such as a "VM PCI Direct Access" driver.

Judging from the ridic[color=#ff0000;]i[/color]lous, it already creeped in :ph34r:

 

Lay down, relax, see if your blood pressure gets stabilized.... :)

Yoy!

Medevil, have a cold beer on me. Also those involved.

 

Xpmode was relating to win7 64, my error.

Vms was the last idea, at this point I can't remember details. I too am tired of this.

As said there is a small linux distribution, which does what I want.

Old desktop,serial. Old is gold, as you said!

Anyway, to add to anyone who ever wants to read this,

- the software wants ircom

-there are no dos palm software

-there are no ir drivers for dos.

 

10 dec: search http://translate.goo...ved=0CGsQ7gEwCQ .(Win2K, try if you want.)

and http://translate.goo...ved=0CGsQ7gEwCQ read if you want.

Last url links as prev one. It was meant as post 5 of same link. (or, http://sourceforge.n...jects/ircomm2k/)

Also, http://www.google.co...chrome&ie=UTF-8 . Seems to relate to xp, 2000, or win7 64.

http://msdn.microsof...esktop/ms691775(v=vs.85).aspx

 

 

 Instead of IrCOMM, Windows Sockets is the recommended programming interface for IrDA on all Windows platforms.

(10/2012)

Links to .net, etc. Not a simple thing.

Also documents about compiling stuff, etc.

 

 

 

Well in fact, the most "natural" method I can think of is to use IRP_MJ_READ and IRP_MJ_WRITE. But not all devices support these.

 

Leads to:

If noobs like me wanna read, -serial (qEMU): http://blog.zhangsen...-from-qemu.html

These postings are just for the sake of interest.

And also: http://alien.slackbo...=slackware:qemu . Good read.

If you need to create a virtual COM port connection, you can try the software http://www.eltima.co...oducts/vspdxp/ or maybe you need to access virtual serial port or your COM port over the network - follow these instructions http://www.eltima.co...irtual-machine/

Sure, it is only US$ 99.95 for a license, after the 14 days trial.

 

It is very nice of you to have taken the time to register on the board to post on a 4 years old topic about this Commercial (and not even "cheap" ) Virtual Serial Port driver.

I believe that there are anyway some Freeware alternatives.

I have a similar question:

 

Do virtual USB drivers exist? I've always thought it would be nice to be able to trick a program (ex. Win32DiskImager) into thinking that a raw image file, masked as USB flash drive, were plugged in, so that I could write to it, instead of risking a real USB (all of which are in use for booting other stuff). I havent found any such drivers, outside of those found in VMware, VirtualBox, etc. If something like a disc drive can be emulated in software, why not USB-related stuff?

You probably want a virtual host controller interface.

Check:

@ Your 2nd link seems to be mostly suited to people who want to share a USB (whether real or virtualized or both, I cant be sure) via a network. I dont care about sharing via a network (although it could become useful later).

 

The first link doesnt seem to have any real documentation other than a description, and only seems to work in Linux (the SourceForge page says the Windows version basically isnt functional yet).

 

Are there any other options? I always kind of figured that something like a virtual USB driver would be in high demand, kind of like disc mounting softwares, but apparently not.

Well, it has in practice no "real" use, (if not that - as the given links are more or less about) virtualizing the USB for "transporting" a "real" device over TCP/IP (or other  remote protocol), in all other cases (including particularly disk like devices) it makes little sense to virtualize the controller, you are after the actual device (i.e. the disk) and you can get rid of the unneeded added layer of the USB protocol and virtualize directly the disk (at volume filesystem level like IMDISK does or at Storport/SCSI miniport level, like Arsenal Image Mounter does, to give you a couple examples).
