Abstract: Frame collisions on communication channels connecting half-duplex units and a full-duplex unit are avoided using MAC and LLC layer protocols adapted to arbitrate channel usage. One or more flags can be included in MAC and LLC packet headers and/or acknowledgements to indicate whether subsequent packet transmissions will be attempted by sending units. Units receiving set flags can hold off transmission until receiving cleared flags from the sending units. In this manner, packet collisions can be avoided.
