`EEC 8885: 1993. These standards define a multiplicity of
`point-to-point and multidrop protocols. These include both
`master/slave and peer-to-peer types of data links, employing
`both half-duplex and full-duplex methodologies. (For the data
`link-portion of this standard, a particular subset, known as
`TWANRM, is utilized. TWANRM defines a half-duplex mas-
`ter/slave variation of HDLC). (EMB/MIB) 1073.3.1-1994
