+ * sercons.c
+ *      choose the right serial device at boot time
+ *
+ * triemer 6-SEP-1998
+ *      sercons.c is designed to allow the three different kinds 
+ *      of serial devices under the decstation world to co-exist
+ *      in the same kernel.  The idea here is to abstract 
+ *      the pieces of the drivers that are common to this file
+ *      so that they do not clash at compile time and runtime.
+ *
+ * HK 16-SEP-1998 v0.002
+ *      removed the PROM console as this is not a real serial
+ *      device. Added support for PROM console in drivers/char/tty_io.c
+ *      instead. Although it may work to enable more than one 
+ *      console device I strongly recommend to use only one.
