- All other link definition fields except Level 3 numeric parameters are left unmodified.
Note: TxX25LinkL3Opts assumes that the packet is already a properly initialized Define Link packet. Applications should call TxX25LinkDefault and TxX25LinkDefine prior to calling TxX25LinkL3Lcn to assure that the packet contains all the proper default and required values.
- Applications should only call TxX25LinkL3Lcn when non-default values of these parameters are needed. These values are set to default values by TxX25LinkDefault.
