How to shut off fifo using CVI?

[TheSpecialist]

I need to programatically turn off the FIFO function on the comport.  How can I do this using CVI?

Hello "The Specialist",
       I am by no means a COM port expert, but I think that you will probably have to access your operating system's API to control low level settings on the COM port.  If you are using Windows, you should search msdn.com.  Let us know what you find out.  Why do you want to disable the FIFO for?

Cheers,

I need to shut off comport fifo so certain devices connected to the RS-232 port can communicate correctly.  Are there any examples of windows SDK command configuring comports in CVI?

Hello Joncombat,

I wasn't able to find a CVI example that would accomplish your requested task. As Nathan mentioned you will need to use Windows Serial API to manage your port communication. I was able to come across this operation while searching MSDN and it appears to set the FIFO control register.
