Labview as terminal (RS232)

[thls]

I want to read data from the serial port, but because I want to use it as terminal I don't know how many bytes are send.

(I think I solved that issue with the attached code)

My device sends several lines of data but I want to have it presented in a windows line by line and that does not work.

Can anybody give me some advice how to change my VI?

You're missing the attachment.

No attachment, but here's how I would do it: use a producer loop to read the serial port (the Bytes At Port property may come in handy) which will message a consumer/GUI loop when (an) EOL character(s) is detected. That way, the GUI doesn't know about any incoming data until you've qualified it as "ready" to display. The downside to this is that the application may appear unresponsive while it's waiting for a complete response from the device.

Again but now with attachemant

reading rs232.vi

[todd]

That vi does not do anything with the serial port - nor does it split a string into lines. Perhaps it is the wrong vi?

You should update your profile, which says you are using LabVIEW 7. You posted the VI in LV2011.
