OKIE DOKIE, problem solved!

First of all I'd like to thank MVP John Cena for his concern, he was the one
that found the guilty setting, lol, thanks a lot, you did it!

One important thing to notice is that LPT port settings must be set to EPP,
not ECP, or the scanner won't work as I expected. The thing that was avoiding
to get detected by Virtual Win98SE was the enabled Hardware Virtualization
box.

Once I disabled it, the scanner was perfectly detected and installed by
Virtual Win98SE with its drivers.

I still don't get why ECHO commands @ Win7 fail but what the helI, it's not
important anymore! At least till now, lol. And the most amazing thing is that
even with the Printer Spooler SVC ENABLED, the old scanner still works. (?)

Once again thanks a lot for your help.

Regards,
Bart

Where did you set this? I cannot find any such setting when I look in
VPC2007 or on my host device manager...

I don't have a VT capable CPU so I don't have that checkbox anyway.

How is the ECHO (= ping?) command connected to the printer port
problem?

That's really strange. My experience is that if the print spooler is
running it grabs the LPT port and it is then impossible to transfer it
into a VPC guest....

You have to set the parallel port mode at the BIOS of the host
computer. MS-VPC2007 will only let you enable or not the parallel port
access to the virtual machine. It's funny to realize that dispite the
drop-down box you can only choose one address for the LPT port which
is 378f-378h.

Sorry, I have no idea then. Here the box is "usable" but if it's
checked the scanner simply doesn't work.

> How is the ECHO (= ping?) command connected to the printer port problem?

A long time ago we could send command straight to the ports. I.e.:
echo ata > com2 would make the modem pick up the phone and answer (of
course, assuming the modem runs on COM2). If the command is refused
then it looks like something is blocking the port (which in my case I
have no idea of what it is)

Well, don't know what to say. It just works, lol.--

OK, then I understand. It will be a while before I can check that
because I never reboot my PC unless absolutely required (once every 3
months or so).

I only mentioned this to say that since I have the old CPU I cannot
check this behaviour....

Well, if it works then it does... :-)
