Integrating PuTTY into Labview

[ErikaE]

But it accepts some other commands

G for GO (use current motion profile)

H for home

N for enter number of steps

C for enter Clockwise or Counter

etc......

why would it some and not others?

My guess would be that you probably have a timing issue. It would help if you could try to post your code, assuming the issue with attachments doesn't screw things up. Try posting your code.

The basic serial port example in LabVIEW is pretty limited - it only does a single write and a single read.  Are you using that example directly with no modification?  If you're using the Excitron Au Controllercoder it looks like some of the commands require more interaction than that.  Several of those command expect you to send a character, wait for a response from the controller, then send more characters.  This won't work well with the basic serial port example.  Also, the manual says "After all input is received, the Au
Controllercoder will send a LF (line feed), CR (carriage return), Axis address, and a prompt '>‘."  The basic serial port example sets the termination character to LF and enables it, so the VISA read terminates when it reaches the LF character, preventing you from seeing the rest of the response.

Thanks, I think its because I was lame and tried to use the serial port example "as is"

We have developed a package on the LabVIEW Tools Network to automate serial port interactions. You can use it to replicate what you manually do using Putty in LabVIEW for serial devices such as logining in, entering commands, waiting for a response and returning it.

PLEASE, 

Could you attach your VI?

i have a similar problem and I can not solve it.

thanks.

Hi Aitorplaza - Since this forum post is more than a year old I would recommend posting your question in a new thread. That way it will get more visibility from users. You can reference this thread in your new post!

Not clear for me... is there a VI that can be called from Testand for serial/ssh/telnet communication?

[ALAB]

Yes. For Telnet, you can just create a VI and use LabVIEW's TCP VIs. For serial you can also use NI VISA or the "AutoSerial toolkit" which is easier. For SSH, you can use the "Alab SSH" toolkit. You can find these toolkits on the VIPM (VI Package Manager). They all come with some sample code.
