That was the name of the dir. (Sorry,that was probably confusing.) Capture was done with a NADs box since it would be successful. What I was seeing during testing was loading DOS100.CO from the UR2 didn't an FDC Emulation mode command (M1) and the PDDuino didn't seem to know how to proceed without having the dmeLabel set. If you run through one cycle with TS-DOS where it does check for FDC, everything works after that point. So I think there is something broken in the routine to allow for a non FDC Emulation request, although I haven't been able to nail it down yet and I did majorly screw everything up trying to "improve" debugging before.. Lashing together a modular test setup now with the serial port broken out for capture. Should make it easier to get a full capture of the issue. Brian
