1, 2, 3... 1.
Errors that occur in Host Link systems are classified into the following three cate-
gories:
2.
3.
Programs to monitor communication times and error handling need to be devel-
oped on the host computer. Be sure that these include processes that can re-
spond appropriately to errors and other abnormalities from the PC by taking into
consideration the kinds of errors described in the sections listed above. An ex-
ample of the logic processes that need to be considered is given in the in the
following flow-chart.
Errors indicated by the Host Link Unit (see 5-4 Troubleshooting).
Errors processed by the PC (see the Restart and Error Flags sub-section
for each group of models in Section 2 Host Link Unit Characteristics).
Errors processed by the host computer (see 5-2 Error Control, 3-2 Commu-
nications Protocol, and all of Section 4 Commands and Responses, espe-
cially 4-35 ABORT and INITIALIZE, and 4-45 Response Code List).
