Rein, On the re-send of missing blocks issue, without testing, just by looking at the server's code, may I suggest the following changes in "sub handle_rxqueue": 1. move the "$cntruns++;" statement in the else part of the test for good frames. The logic being is that we would stop after having found 8 missing blocks, not just after checking 8 positions for missing blocks. The current code is consistent with the behaviour I found: only the first few missing blocks are requested, not all (or at least up to 8) of the missing blocks. 2. I think we should remove the section below, since it is possible to have missed 8 blocks, but received the status block OK, or have accumulated 8 missing blocks. The test in 1 above would in any case limit the number of missing blocks (there is also a missing string truncation for that purpose): if (length ($MissString) == 8 && $Iamserver) { $MissString = ""; $HisLastblock = $Goodblock; } Sorry but I don't have time to test that code.
