Termination Character Doesn't Change

[nevica]

Hello, I am using vi to set, send and check a serial port. When I try and change the termination character on the front panel from 0xA (\n) to 0xD (\r) and try and step through the vi I find that the termination character consistently reverts back to 0xA which is not what I want. What am I doing incorrectly.

Hi nevica,

you don't set any termination char in the "VISA Configure serial port" vi. Here's the place to do so! (Just switch on the context help...)

You also send us a vi which is calling a vi with the same name recursively. That is not supported by LabView...

Hint:

You should also state the LabView version you're using, especially when working with these old ones... (Your vi is LV 7.0.)

Hello Gerd,

Thanks for your reply. In "VISA Configure serial port" .vi I set the termination character to 0xD (\r). <<<<<BUT>>>>> when I run the vi by stepping through or run it as a whole vi the termination mysteriously reverts back to 0xA.

Why is this. I'm using LabView 7 Express.

Hi nevica,

that's what I see in LV8.6:

You don't set any temination chars here... Maybe someone with LV7.0 should check this (my 7.1 is only available at work...)

You do not connect anything to the termination char input (on the serial port config vi) so the default value is used not the current value, then this vi is called. This is standard Labview behavior.

Hello,

Please use the termination char terminal on the VISA Configure Serial Port VI:
