All of above with Kfloppy

I've run into this on PC's with Windows 7 or newer and Fanuc software rev 4.3 or older. I'm guessing it has something to do with permission to delete the contents of a folder.

Kfloppy is a DOS program (I wrote it years ago). Try running the product under DosBox. Its a free program that runs old DOS programs under Windows.

how do you get it to run on dosbox? I seem to be having issues with settings of the serial port for dosbox

You can run Kfloppy under Win7 if it is a 32 bit version.
and I posted this elsewhere but just in case I am repeating it.
IF the kfloppy protocol was written based on any kind of standard commands. Could someone post the definitions of
RTR , RQS, SLF, DFF, DLF, CLR, RTS

SLF seems to indicate transfer the file name that follows.
I am clueless on CLR, DLF and DFF they seem to do something as well relative to a file name.
RTS seems to request a certain number of bytes. i.e. ( Request to Send) If these are standards of any kind and someone can post
the details I would appreciate it.

Thanks
