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.

Subject: linux ioc console
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.
