[CentOS] TCP port to TTY/Serial Port?

  Thanks for reply!
  Here's the actual scenario:

I have a system running an application which wants to get its data from a physical serial port.   My goal is to provide this data from a network connection, and ~trick~ the application into thinking it's still getting it from the serial port.  Technically it is still on the serial port, but the data is arriving via TCP.
So, it's all on the same machine.   The idea would be for the machine to run an application, pointed at the serial port.  My netcat would receive the data being pushed to it on a TCP port, and redirect it to the serial port.

If life gives you lemons, keep them-- because hey.. free lemons.

Is this on the same machine? I.e. you have only one machine and one 
serial port?

Do you have some sort of loopback cable connected to the serial port?

If it is on two different machines I would check handshaking settings
on the serial ports.
