- /*
- * 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.
