Comment 27 for bug 1676763

Thanks Jakub for the debugging work you put there and the fixes! I've upload now those changes to the current 'focal' Ubuntu serie (tweaking a bit the packaging, I merged the fixes in the patch doing the rewrite in C rather than stacking patches)

Some notes/questions

- the fixes look like they would be good to have in Bionic, for that we would need the bug to be SRU compliant first though (https://wiki.ubuntu.com/StableReleaseUpdates), which means to include a testcase which can be used to confirm the problem and that the fix work.

If someone having the issue would like to write that it would be nice (I guess it requires access to a specific hardware?)

- the patches are still not enough to make the modem work or are they? you said the second issue exists upstream still?

- we could reconsider dropping the rewrite but bringing a TCL stack even small, only for that one source has a cost in ISO size/maintainance (if we install tcl then we need to maintain it)
