Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

|
|
* 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.
