You mean "Drip Feeding" (Fanuc refer to this as "Tape Mode")
EasyDNC/RemoDNC does not have or need any special setting for drip feeding. Just ensure flow control in DNC Setup is set to XON/XOff.
Also in DNC setup make sure the checkboxes "Wait for CNC Start cmd" and "AutoRepeat" are both empty (Not ticked)
Your CNC console may have a switch or dial with "Tape Mode" written on it.
Get the program in the PC ready to send but do not press the send button.
Go to the CNC, Select Tape mode then 'Cycle Start'.
Go to the PC and press the 'Send' button.
As data starts to flow the machine should start cutting.
The very first time you do this I would try it with a very small program. Maybe just one line with a small move in the air.
Once you have that working you can try with a bigger program.
If you get Overrun/buffer over flow allarm at the CNC then go back to DNC setup and increase block delay (bigger number). If that doesn't help then you may need a lower baud rate. But if the baud rate is too low the machine might start jerking. It's a kind of balancing act and adjusting baud rate and block delay till you get it just right.
