- All X.25-specific fields are set to their default values. All common interface definition fields are left unmodified.
Note: TxTpxIfX25 assumes that the packet is already a properly initialized define interface packet. Applications should call TxTpxIfDefault some time prior to calling TxTpxIfX25 to assure that the packet contains all the proper default values.
- Applications should call TxTpxIfX25 when a packet is to be used to create an X.25 interface for the first time or when returning to X.25 interface defaults.
