I have a simple server that we are using for our soft IOCS.  It is
written in c++.  Essentially you start procServ with a port number and a
path to a shell script that will start your soft IOC.  The procServ goes
into the background and starts the IOC on a PTY.  You can access the PTY
using telnet to the specified port on the local host.  If you need to
reboot the soft ioc just login and send it a ^X.  If the soft IOC dies
it will be restarted after a short delay. Multiple connections can be
opened so you can use bash constructs like /dev/tcp/localhost/7000 to
just monitor or setup log files.

It has one minor bug which I need to fix sometime, when you are using
some of the sequencer's interactive commands you will need to send it a
line feed instead of a carriage return.  I think that has to do with how
the sequencer sets up its tty port when doing the single character IO.

Hi,

We were wondering how other sites handle the console on a linux ioc.  
The linux computer in question does not have a monitor attached as it is

accessed remotely.  Either we need to run the IOC with no shell (iocsh) 
or we need some mechanism to login and connect an iocsh shell.
