It's part of the config-register set... Out of the 16 bits that represent
the config-register (like 0x2142), bits 11 and 12 represent the console
speed.
There are four possible settings on 25xx and 4xxx routers. They are 1200,
2400, 4800 and 9600.
Bits 11/12 Speed
0 0 9600
0 1 4800
1 0 1200
1 1 2400
This means that the overall register can be a pain in the ass to decode
since those bits fall in two separate digits.
Assuming that you want config-register to be 0x2142 for normal operation.
If it's 0x2142 you're at 9600.
0x2942 is 4800
0x3142 is 1200
0x3942 is 2400
Enjoy! But remember you will have figured out what speed it's at already
(unless you telnet in), but 0x2142 will get you back where you want to
be....

I see you point. There is only like 4 speeds it can be. However , if they
change the speed you need to be able to change it back.
I know I saw a list somewhere that explained what each of the bits did. I
just cant remember where I saw it.
