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