Last change on this file since 204 was 200, checked in by gregli@…, 13 years ago

Added logic to skip scanning COM ports if a COM port was already found during the normal detection process, to avoid finding the same serial drive twice and preseting the OS with two drives which in reality point to the same physical file on the server. Also added logic to skip scanning for the slave serial drive if the master was not found. And various small optimizations.
