Sorry it took so long I've been hack a bunch of code.

I need something that will take a line and determine what command the
user want to attempt. I will guess there are only 2 commands a set and
a get (If anyone can think of others let me know).

The next part is the addr= and the last part is the value=.

The addr= has format of <interface>.<point>[.<item>[.<item> ...]
Each entry will be ascii numbers (literals 0-9 n amount of times up to
the '.') so it can be typed in from a telnet.

The value= has a string format terminated by a null (the null will not
need to be sent). The string may need to be converted into a number or
stored as a string. This way we can send strings with escape sequences,
hmm we may need to support being able to send \xxx sequences. Should we
translate them of just accept the 8 bit character? I know there are some
8 bit characters I can't send from telnet. So I guess we need escape
character support.

This was taken from Jay Hogg's recommendation, I hate it because it's
hard to remember (and !12000200 is?) but it is simple and I think it
covers all types of commands that can be sent. Maybe instead of value
we can change that to num= , str=, hex=, oct=, etc?

Hey this is becoming more object oriented!
