6100 BSC Programming Manual

Writing Applications that Use 6100 BSC
The response buffer format is:
Response := 64
Status := 0 if the request was successful, otherwise
a code for the error that occurred
Request ID := The same as in the request
Detail := A code containing more status information
Text In := 0
Text := None
NOTE
If a WRITE request completes with a retry error (status code
162, 172, 173, or 175), the line remains in WRITE state.
Therefore you may repeat the request, but that action is
normally pointless. A better practice is to send an EOT and
issue another line bid; if the line bid fails, there is
probably an equipment malfunction.
The retry count has an impact on the number of retry errors.
Set a retry count that is high enough to accommodate the
equipment you're using; remember that you can change the
count online with the SETMODE request.
