Hi,

Thanks for the suggestions.
I checked ln sources once again and it turns out that ln didn't want to work
under the LFN driver only. It works when the driver is not installed. .The
newest version of LFN  I'm working on completely bypasses int 21h AX=6Ch
call and creates/opens files using Win32 CreateFile() call. It turns out
that DOS file handles returned by the LFN driver under some circumstances
are not recognized by int 21h, AX=4400h used by get_dev_info() call. which
returns 0 instead.

I'm working on this right now and wonder if the SFT layout under Windows NT
is anywhere documented ....
