vrf Communications changes

Question asked by VRFuser on Mar 28, 2006

I think you can just do the following:

1) Talk to the instruments that have the common setup
2) Perform an Execute Close on the serial port using Direct I/O
3) Talk to the instruments with the other setup
4) Perform another execute close.
5) Repeat

I have done this when I used a common serial port with two programs and needed to release the port.

Define two serial instruments, one with no parity and one with even parity. Try communicating with one. Feed an error pin to a close transaction and then try the other. You can do the same thing by varying the parameters dynamically, but the port has to be closed when you change parameters.
