Greg, This v2 respin removes the dependency on the patch to which Alan objected (regarding not hanging up remote serial console modems). This patch fixes bugzilla #69751, where the serial console is garbled after resume from suspend. Although this was originally reported as a regression, this bug is actually caused when a user-space process (such as setserial or stty) opens and then closes the associated tty. The resultant tty port shutdown caused the console termios settings to be lost, and thus uninitialized when the console was subsequently suspended and then resumed (and there was not an associated open tty). This patch preserves the cflag settings from the associated tty as the console cflags (which reflect the current line settings anyway). The console cflags are already used to restore the console line settings if there is not an associated open tty. The side-effect of this patch is that the serial console line settings are persistent. Originally, only the first-time initialization of the associated port inherited the console line settings; now, each time the associated port is initialized to the most recent line settings.
