Hi,

I posted two days ago about this subject and it seems nobody has experience in dealing with this problem.


The problem was loading MS DOS environment such as mode comX in windows XP.

I added on the last line of autoexec.nt the code MODE COM4:4800,n,8,1 and launching the legacy application still fails. Basically the application will check if can communicate with the encryption card, this encryption card uses com port but it doesn't work.


Running an instance of command.com within windows, will give me an error "Bad command or file name". This means that the mode command on autoexec.nt is not working even though the path is correct. I even go to the extent of debugging this mode.com and I found that the said version will not run in dos mode.


I ask members of this community who had encounter this problem and successfully solve it to share and help others like me.

BTW, the legacy application is written with CA-Clipper 5.2, is there a free ware that can decompile a clipper app exe?


thank you.
