When the OSTC receives the download dives command, it responds immediately with the preamble bytes. But then it does a linear search through its internal memory to locate the end-of-profile marker. As a result the response time increases when the marker is located near the end of the memory area. In the worst case scenario, the response time can exceed the 3 second read timeout with a few milliseconds. Since the required timeout depends on the total amount of profile memory, this problem was indirectly introduced with firmware v1.91, which doubled the amount of profile memory from 32K to 64K.
