We study the roughening, the preroughening, and the orientational roughening transitions for interfaces between phases in the isotropic competing Ising Hamiltonian H=-JΣnmsisj-2M Σlnnnsisj. The symbols, NN, DNN, and LNNN represent nearest-neighbor, diagonal-nearest-neighbor, and linear-next-nearest-neighbor pairs, respectively, with J>0 and -∞
