1 | /* |
| 2 | * sercons.c | |
| 3 | * choose the right serial device at boot time | |
| 4 | * | |
| 5 | * triemer 6-SEP-1998 | |
| 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. | |
| 11 | * | |
| 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. | |
