The plan is for the software to put syndrome commands among the output headers in OHR. Each time the transmitting hardware sees one of these it transmits the current syndrome that may reach the receiver in the next node where the hardware will be able to detect errors and perhaps where the software can sometimes repair transmission errors. In any case a syndrome report will appear in the IHR. A small number, provided by the software in the syndrome command is transmitted and recorded in the syndrome report. I plan to use this as a syndrome serial number. Presumably no header packet is processed until the following syndrome has been seen. The software can adjust the frequency of these error syndromes dynamically. I can think of many variables that might influence this frequency.
This is one plan.
