I have a computer linked to an instrument via RS-232.
On the computer, the software controlling the instrument is sending commands to the instrument and retreiving the data from the instrument.
Somehow, I need to be able to treat this data live, but I cannot
1) stop the software 2) modify its codeUsing an Hyperterminal-like program, I was able to "monitor" the communication between the software and the instrument. i.e. see the data being sent back to the software. Eventually, this causes a communication failure between the software and the instrument. I'm guessing that the instrument is maybe receiving queries from both the software and hypertermal at the same time (although I'm actually not typing anything in hyperterminal).
Anyway the question is: Would there be a way to run another program (e.g. a matlab script) in parallel with the software and that could "listen" to the com port (without interfering) ?
