commit 5053221822cf1365a69ba8983c66adef1d291dd0 Author: Patrick Georgi patrick@georgi-clan.de Date: Wed May 30 00:17:12 2012 +0200
Move SerialICE protocol support to separate file
serialice-com.c is responsible for the lowlevel details of communication. serialice.c does the hooks and lua coordination.
No changes were made to functions operation. Two unused functions are #if 0'd out, and there's some reordering going on to make gcc happy, but any change inside a function is a bug.
