SDLC HPAD Port Trace Example
The following is an example of an SDLC HPAD (level 2) port trace - Controller
Address 03 Modulo 8 Link Activation and SNA PU and LU (Destination Address
Field 02) activation. Note that th is controller is but 1 on a 3 drop multipoint line. The
other 2 are addressed 01 and 02 and are in Normal Response Mode already (activated
and exchanging Receiver Ready's).
