diff BootLoader/Src/tComm_mini.c @ 1044:9d9d506a82d3 BootloaderOstc5

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Bugfix BT init sequence: Some older steps which were related to OSTC were deactivated (to be removed) and a command for the second echo step was missing. in addition two stps for switching the power of the modul before the sequence starts have been added to have a defined starting point.
