This patch set has been brought up to date with cvs and the time stamp 
feature is abstracted now.  This means you can do something like:
-serial mon:vc

Or my favorite:
-serial mon:telnet::4444,server


----------------

There are two patches attached to show the logical progress of the code 
and in the case that one is not accepted the work is more easily broken 
down.

The serial_mux_driver.patch must be applied first.  It adds a generic 
mux support for the I/O drivers internal to vl.c.  The main purpose is 
to use it for switching on the monitor.  Basically it allows more than 
one driver to register an fd_read and fd_can_read routine.  Of course 
the mux support is generic and could easily be used for other sorts of 
I/O.  This patch also adds the new options:

-echr ascii_value -- Allow you to use a different control character 
other than Control-a
-serial mon:device_string  -- Multiplex the device_string with the 
monitor functionality

The second patch fully abstracts the monitor and time stamp functions so 
that the monitor can be used on more than one serial port at the same 
time as well as having a separate dedicated monitor.  I also removed the 
stdio splitting from the stdio driver.  The mux driver can be used to 
replace any functionality that previously existed.
