Changes in the past have tried to fix the issue but one way or another they do not seem to work consistently across all computers and systems. Therefore I think by default the _strict argument should be set to False unless specified to prevent the faulty behavior from producing false timeouts. There are two possible reasons why I think this feature may never work correclty: * One the OS handling the timeout incorrectly if more than one character arrives at the same time if it is busy doing something else. * Another one as described here https://stackoverflow.com/a/37053542/1813498 is the fact that the timeout value must be a multiple of 0.1. At 9600 the inter char value is calculated to be 0.00171875 and then rounded to 0 so therefore it will not work correctly. The conclusion from my side is that it is not possible to accurately measure this timeout and should perhaps be removed. At least it should be by default disabled.

The first entry is then used as a "default" for the reset() call, which seems rather at odds with the "sparse" nature. Instead, use a supplied intial value if provided, and use that to properly reset the store to _that_ value. Similarly don't require an initial list at all, allowing addresses/registers to be filled in via follow up calls to .setValues() Example old code: (We want to register 20 addresses at 0x2000} # must provide at least one initial value! hr = ModbusSparseDataBlock({0x2000: 0x55aa}) # actually register what we want using flexible lists. hr.setValues(0x2000, [0]*20) Example new code: hr = ModbusSparseDataBlock() hr.setValues(0x2000, [0]*20) Example old code using reset: hr = ModbusSparseDataBlock({ 0x2000: 0x55, 0x3000: 0x66 }) hr.reset() At this point, the store contained two registers, 0x2000 and 0x2001, both containing the value 0x55. This hardly seems to have been the intention of .reset() on a Sparse store, but is obvious for the sequential store.
