The following flowchart shows the computer decision making processes for en-
suring that the PC is in RUN mode after start-up.
Host Link Units use some of the Special Relay (SR) area and Auxiliary Relay
(AR) area bits of the PC to restart the communications control program of the
Host Link Unit and to indicate the occurrence of communications errors between
the Unit and the computer. The word (Wd) addresses and bit numbers of these
bits are as follows:
