DIGI-NOT-OWN [7] This function causes the TNC to never digipeat a frame that was originated with that TNC's MYCALL. It prevents multiple repeating of the same frame due to multiple alias callsigns.
DIGI-ONCE [7] This function causes the TNC to only digipeat a frame once when it finds its MYCALL in the path and the "has been repeated" bit is on.

DIGISent [6] none Digipeated frames sent counter
DIGI-SWAP [7] This function causes the TNC to replace the alias call in a frame with the MYCALL when the TNC digipeats a frame. This allows subsequent stations to know the real path taken by the frame so that a reverse addressed frame may be sent back. It also puts valid packet station identification in the frame.
