Hi Sergey,

I am not shure. But, I think to produce the deal in DOS mode is easier than WINDOWS.

I saw a long time ago on the WEB at Microsoft´s site (I think) an article with some samples with that.

It´s something like OPEN in a low level format using the name of file "COMx:" and then produce all the FREADs and FWRITEs.

Try search at the MSDN, maybe you will find it.
