If Install this in Win 2K system, the driver file VCOM.SYS is not copied to
Driver directory. What is the modification needed for this INF file.

One more thing, How can I do the Unit Test for this Virtual Driver. How can
I load my driver…? Any sample driver loader available…?

Hello,

If Install this in Win 2K system, the driver file VCOM.SYS is not copied to
Driver directory. What is the modification needed for this INF file.

change

[DriverCopyFiles]
VCOM.sys,2

to
[DriverCopyFiles]
VCOM.sys

One more thing, How can I do the Unit Test for this Virtual Driver. How can
I load my driver…? Any sample driver loader available…?

The installation itself loads the driver. Later you can use the
DiSetupApi to load/unload the driver at runtime. (see ddk devcon
sample). I assume you have a WDM driver.
To Test your driver use hyper terminal or other serial
COM interface based application or RAS based on modems.
