/*
 * 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.
